* remove ugly prng from mk*temp and just re-poll time on retryRich Felker2011-07-281-6/+5
|
* eliminate mk*temp dependency on snprintfRich Felker2011-07-281-3/+4
| | | | | this helps some tiny programs be even more tiny, and barly increases code size even if both are used.
* another return value fix for mktemp...Rich Felker2011-06-121-1/+2
|
* make mktemp match the historic behavior, and update functions that use itRich Felker2011-02-191-1/+2
| | | | | | the historic mktemp is supposed to blank the template string on failure, rather than returning 0. just zero the first character so that mkstemp and mkdtemp can still retry with O(1) space requirement.
* major improvements to temp file name generatorRich Felker2011-02-181-13/+15
| | | | | | | | use current time in nanoseconds and some potentially-random (if aslr is enabled) pointer values for the initial tempfile name generation, and step via a cheap linear prng on collisions. limit the number of retry attempts to prevent denial of service attacks even if an attacker can guess the filenames.
* ensure standard functions mk[sd]temp don't depend on removed function mktempRich Felker2011-02-141-1/+3

* initial check-in, version 0.5.0 v0.5.0Rich Felker2011-02-121-0/+29
