| ZStream Constructor | Overloaded. |
| Name | Description | |
|---|---|---|
 | adler | Current checksum value (Adler or CRC32). |
| avail_in | Number of bytes available in the input buffer. |
| avail_out | Number of free bytes remaining in output buffer. |
| msg | Description of the last error (null if no errors). |
| next_in | Input buffer. |
| next_in_index | Position of cursor into input buffer. |
| next_out | Output buffer. |
| next_out_index | Position of cursor into the output buffer. |
| total_in | Total number of input bytes read so far. |
| total_out | Total number of bytes output so far. |
| Z_BUF_ERROR | No progress possible or no room in output buffer. |
| Z_DATA_ERROR | Input data is corrupted (wrong format or checksum). |
| Z_ERRNO | File error. |
| Z_MEM_ERROR | Not enough memory. |
| Z_NEED_DICT | A preset dictionary is needed at this point. |
| Z_OK | No error. |
| Z_STREAM_END | End of stream detected. |
| Z_STREAM_ERROR | Stream structure is inconsistent (input/output buffers are null for example). |
| Z_VERSION_ERROR | Incompatible ZLIB version. |
| Name | Description | |
|---|---|---|
 | deflate | Compresses as much data as possible, and stops when the input buffer becomes empty or the output buffer becomes full. |
| deflateEnd | Frees all dynamically allocated data structures for this stream, discards any unprocessed input, and does not flush any pending output. |
| deflateInit | Overloaded. Initializes the internal stream state for compression. |
| deflateParams | Dynamically updates the compression level and compression strategy. |
| deflateSetDictionary | Initializes the compression dictionary from the given byte sequence without producing any compressed output. |
| inflate | Decompresses as much data as possible until the input buffer is exhausted or the output buffer is full. |
| inflateEnd | Frees all dynamically allocated data structures for this stream, discards any unprocessed input, and does not flush any pending output. |
| inflateInit | Overloaded. Initializes the internal stream state for decompression. |
| inflateSetDictionary | Initializes the decompression dictionary from the given uncompressed byte sequence. |
| inflateSync | Skips invalid compressed data until a full flush point is found, or until all available input is skipped. No output is provided. |
