Detailed Description

Simple single-threaded tool to uncompress .xz or .lzma files.


Function Documentation

static void memlimit_set_percentage ( uint32_t  percentage  )  [static]

Find out the amount of physical memory (RAM) in the system, and set the memory usage limit to the given percentage of RAM.

References lzma_physmem(), and memlimit.

Referenced by memlimit_set(), and parse_options().

static void memlimit_set ( uint64_t  new_memlimit  )  [static]

Set the memory usage limit to give number of bytes. Zero is a special value to indicate the default limit.

References memlimit, and memlimit_set_percentage().

Referenced by parse_options().

static uint64_t str_to_uint64 ( const char *  value,
uint64_t  max 
) [static]

Convert a string to uint64_t.

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

Parameters:
max Return value when the string "max" was specified.

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

Parses command line options.

References display_errors, memlimit_set(), memlimit_set_percentage(), and str_to_uint64().


Variable Documentation

uint64_t memlimit [static]

Number of bytes to use memory at maximum.

unsigned int display_errors = 2 [static]

Error messages are suppressed if this is zero, which is the case when --quiet has been given at least twice.

Referenced by parse_options().
