This version of the library supports only one compression method +// (deflation) but other algorithms will be added later and will have the same +// stream interface. +// +// Compression can be done in a single step if the buffers are large +// enough (for example if an input file is mmap'ed), or can be done by +// repeated calls of the compression function.

If not all input can be processed (because there is not +// enough room in the output buffer), next_in is updated and processing +// will resume at this point for the next call of inflate(). +// +// - Provide more output starting at next_out and update next_out and avail_out +// accordingly. inflate() provides as much output as possible, until there +// is no more input data or no more space in the output buffer (see below +// about the flush parameter). +// +// Before the call of inflate(), the application should ensure that at least +// one of the actions is possible, by providing more input and/or consuming +// more output, and updating the next_* and avail_* values accordingly. +// The application can consume the uncompressed output when it wants, for +// example when the output buffer is full (avail_out == 0), or after each +// call of inflate(). If inflate returns Z_OK and with zero avail_out, it +// must be called again after making room in the output buffer because there +// might be more output pending. +// +// If the parameter flush is set to Z_SYNC_FLUSH, inflate flushes as much +// output as possible to the output buffer. The flushing behavior of inflate is +// not specified for values of the flush parameter other than Z_SYNC_FLUSH +// and Z_FINISH, but the current implementation actually flushes as much output +// as possible anyway. +// +// inflate() should normally be called until it returns Z_STREAM_END or an +// error. However if all decompression is to be performed in a single step +// (a single call of inflate), the parameter flush should be set to +// Z_FINISH. In this case all pending input is processed and all pending +// output is flushed; avail_out must be large enough to hold all the +// uncompressed data. (The size of the uncompressed data may have been saved +// by the compressor for this purpose.) The next operation on this stream must +// be inflateEnd to deallocate the decompression state. The use of Z_FINISH +// is never required, but can be used to inform inflate that a faster routine +// may be used for the single inflate() call. +// +// If a preset dictionary is needed at this point (see inflateSetDictionary +// below), inflate sets strm-adler to the adler32 checksum of the +// dictionary chosen by the compressor and returns Z_NEED_DICT; otherwise +// it sets strm->adler to the adler32 checksum of all output produced +// so far (that is, total_out bytes) and returns Z_OK, Z_STREAM_END or +// an error code as described below. At the end of the stream, inflate() +// checks that its computed adler32 checksum is equal to that saved by the +// compressor and returns Z_STREAM_END only if the checksum is correct. +// +// inflate() returns Z_OK if some progress has been made (more input processed +// or more output produced), Z_STREAM_END if the end of the compressed data has +// been reached and all uncompressed output has been produced, Z_NEED_DICT if a +// preset dictionary is needed at this point, Z_DATA_ERROR if the input data was +// corrupted (input stream not conforming to the zlib format or incorrect +// adler32 checksum), Z_STREAM_ERROR if the stream structure was inconsistent +// (for example if next_in or next_out was NULL), Z_MEM_ERROR if there was not +// enough memory, Z_BUF_ERROR if no progress is possible or if there was not +// enough room in the output buffer when Z_FINISH is used.

(Zero +// would be more efficient, but perhaps a little confusing.) If two +// codes exist, they are coded using one bit each (0 and 1). +// 5. There is no way of sending zero distance codes--a dummy must be +// sent if there are none. (History: a pre 2.0 version of PKZIP would +// store blocks with no distance codes, but this was discovered to be +// too harsh a criterion.) Valid only for 1.93a. 2.04c does allow +// zero distance codes, which is sent as one code of zero bits in +// length. +// 6. There are up to 286 literal/length codes. Code 256 represents the +// end-of-block. Note however that the static length tree defines +// 288 codes just to fill out the Huffman codes. Codes 286 and 287 +// cannot be used though, since there is no length base or extra bits +// defined for them. Similarily, there are up to 30 distance codes. +// However, static trees define 32 codes (all 5 bits) to fill out the +// Huffman codes, but the last two had better not show up in the data. +// 7. Unzip can check dynamic Huffman blocks for complete code sets. +// The exception is that a single code would not be complete (see #4). +// 8.

The most common codes are necessarily the +// shortest codes, so those codes dominate the decoding time, and hence +// the speed. The idea is you can have a shorter table that decodes the +// shorter, more probable codes, and then point to subsidiary tables for +// the longer codes. The time it costs to decode the longer codes is +// then traded against the time it takes to make longer tables. +// +// This results of this trade are in the variables lbits and dbits +// below. lbits is the number of bits the first level table for literal/ +// length codes can decode in one step, and dbits is the same thing for +// the distance codes. Subsequent tables are also less than or equal to +// those sizes. These values may be adjusted either when all of the +// codes are shorter than that, in which case the longest code length in +// bits is used, or when the shortest code is *longer* than the requested +// table size, in which case the length of the shortest code in bits is +// used. +// +// There are two different values for the two tables, since they code a +// different number of possibilities each.

If inflate returns Z_OK and with zero avail_out, it +// must be called again after making room in the output buffer because there +// might be more output pending. +// +// If the parameter flush is set to Z_SYNC_FLUSH, inflate flushes as much +// output as possible to the output buffer. The flushing behavior of inflate is +// not specified for values of the flush parameter other than Z_SYNC_FLUSH +// and Z_FINISH, but the current implementation actually flushes as much output +// as possible anyway. +// +// inflate() should normally be called until it returns Z_STREAM_END or an +// error. However if all decompression is to be performed in a single step +// (a single call of inflate), the parameter flush should be set to +// Z_FINISH. In this case all pending input is processed and all pending +// output is flushed; avail_out must be large enough to hold all the +// uncompressed data. (The size of the uncompressed data may have been saved +// by the compressor for this purpose.) The next operation on this stream must +// be inflateEnd to deallocate the decompression state. The use of Z_FINISH +// is never required, but can be used to inform inflate that a faster routine +// may be used for the single inflate() call. +// +// If a preset dictionary is needed at this point (see inflateSetDictionary +// below), inflate sets strm-adler to the adler32 checksum of the +// dictionary chosen by the compressor and returns Z_NEED_DICT; otherwise +// it sets strm->adler to the adler32 checksum of all output produced +// so far (that is, total_out bytes) and returns Z_OK, Z_STREAM_END or +// an error code as described below. At the end of the stream, inflate() +// checks that its computed adler32 checksum is equal to that saved by the +// compressor and returns Z_STREAM_END only if the checksum is correct. +// +// inflate() returns Z_OK if some progress has been made (more input processed +// or more output produced), Z_STREAM_END if the end of the compressed data has +// been reached and all uncompressed output has been produced, Z_NEED_DICT if a +// preset dictionary is needed at this point, Z_DATA_ERROR if the input data was +// corrupted (input stream not conforming to the zlib format or incorrect +// adler32 checksum), Z_STREAM_ERROR if the stream structure was inconsistent +// (for example if next_in or next_out was NULL), Z_MEM_ERROR if there was not +// enough memory, Z_BUF_ERROR if no progress is possible or if there was not +// enough room in the output buffer when Z_FINISH is used. In the Z_DATA_ERROR +// case, the application may then call inflateSync to look for a good +// compression block. +// + + +int inflateEnd (z_streamp strm); +// +// All dynamically allocated data structures for this stream are freed. +// This function discards any unprocessed input and does not flush any +// pending output. +// +// inflateEnd returns Z_OK if success, Z_STREAM_ERROR if the stream state +// was inconsistent.

(Zero +// would be more efficient, but perhaps a little confusing.) If two +// codes exist, they are coded using one bit each (0 and 1). +// 5. There is no way of sending zero distance codes--a dummy must be +// sent if there are none. (History: a pre 2.0 version of PKZIP would +// store blocks with no distance codes, but this was discovered to be +// too harsh a criterion.) Valid only for 1.93a. 2.04c does allow +// zero distance codes, which is sent as one code of zero bits in +// length. +// 6. There are up to 286 literal/length codes. Code 256 represents the +// end-of-block. Note however that the static length tree defines +// 288 codes just to fill out the Huffman codes. Codes 286 and 287 +// cannot be used though, since there is no length base or extra bits +// defined for them. Similarily, there are up to 30 distance codes. +// However, static trees define 32 codes (all 5 bits) to fill out the +// Huffman codes, but the last two had better not show up in the data. +// 7. Unzip can check dynamic Huffman blocks for complete code sets. +// The exception is that a single code would not be complete (see #4). +// 8. The five bits following the block type is really the number of +// literal codes sent minus 257. +// 9. Length codes 8,16,16 are interpreted as 13 length codes of 8 bits +// (1+6+6). Therefore, to output three times the length, you output +// three codes (1+1+1), whereas to output four times the same length, +// you only need two codes (1+3). Hmm. +//10.

The most common codes are necessarily the +// shortest codes, so those codes dominate the decoding time, and hence +// the speed. The idea is you can have a shorter table that decodes the +// shorter, more probable codes, and then point to subsidiary tables for +// the longer codes. The time it costs to decode the longer codes is +// then traded against the time it takes to make longer tables. +// +// This results of this trade are in the variables lbits and dbits +// below. lbits is the number of bits the first level table for literal/ +// length codes can decode in one step, and dbits is the same thing for +// the distance codes. Subsequent tables are also less than or equal to +// those sizes. These values may be adjusted either when all of the +// codes are shorter than that, in which case the longest code length in +// bits is used, or when the shortest code is longer than the requested +// table size, in which case the length of the shortest code in bits is +// used. +// +// There are two different values for the two tables, since they code a +// different number of possibilities each. The literal/length table +// codes 286 possible values, or in a flat code, a little over eight +// bits. The distance table codes 30 possible values, or a little less +// than five bits, flat. The optimum values for speed end up being +// about one bit more than those, so lbits is 8+1 and dbits is 5+1. +// The optimum values may differ though from machine to machine, and +// possibly even between compilers.
