Function Documentation

lzma_bool lzma_lzma_preset	(	lzma_options_lzma *	options,
		uint32_t	preset
	)

Set a compression preset to lzma_options_lzma structure.

0 is the fastest and 9 is the slowest. These match the switches -0 .. -9 of the xz command line tool. In addition, it is possible to bitwise-or flags to the preset. Currently only LZMA_PRESET_EXTREME is supported. The flags are defined in container.h, because the flags are used also with lzma_easy_encoder().

The preset values are subject to changes between liblzma versions.

This function is available only if LZMA1 or LZMA2 encoder has been enabled when building liblzma.
