Function

compression_stream_init

Initializes a compression stream for either compression or decompression.

Declaration

compression_status compression_stream_init(compression_stream *stream, compression_stream_operation operation, compression_algorithm algorithm);

Parameters

stream

Pointer to an allocated compression_stream structure.

operation

A constant of type compression_stream_operation used to indicate the stream operation.

algorithm

Return Value

A value of type compression_status, interpreted as follows:

Discussion

After success of this function, set the dst_ptr, dst_size, src_ptr, and src_size fields of the stream structure to their respective values. You can then pass stream structure to the compression_stream_process function.
