Function Documentation

static void set_default_memlimit

(

void

)

[static]

Finds out the amount of physical memory in the system, and sets a default memory usage limit.

References memlimit, and physmem().

Referenced by parse_options().

static uint64_t str_to_uint64

(

const char *

value

)

[static]

Converts a string to uint64_t.

This is rudely copied from src/xz/util.c and modified a little. :-(

References argv0.

static void parse_options	(	int	argc,
		char **	argv
	)			[static]

Parses command line options.

References memlimit, set_default_memlimit(), and str_to_uint64().

uint64_t memlimit [static]

Number of bytes to use memory at maximum.

Referenced by parse_options(), and set_default_memlimit().

const char* argv0 [static]
