Detailed Description

zlib compression options

Initialising gmio_zlib_compress_options with {0} (or {} in C++) is the convenient way to set default values.

Field Documentation

uint8_t gmio_zlib_compress_options::level

Compression level.

Use enum value from gmio_zlib_compress_level

enum gmio_zlib_compress_strategy gmio_zlib_compress_options::strategy

Compression strategy.

uint8_t gmio_zlib_compress_options::memory_usage

Specifies how much memory should be allocated for the internal compression state.

The value must belongs to [1..9] or equals to 0 which maps to the default usage.

1 uses minimum memory but is slow and reduces compression ratio
9 uses maximum memory for optimal speed

void*(* gmio_zlib_compress_options::func_alloc)(void *opaque, unsigned int items, unsigned int size)

Optional function used to allocate the internal state within z_stream.

void(* gmio_zlib_compress_options::func_free)(void *opaque, void *address)

Optional function used to free the internal state within z_stream.

void* gmio_zlib_compress_options::opaque

Optional private data object passed to func_alloc() and func_free()
