2013-12-12include cleanups: remove unused headers and add feature test macrosSzabolcs Nagy1-2/+2
2013-08-02fix (deprecated) mktemp logic and update it to match other temp functionsRich Felker1-4/+11
the access function cannot be used to check for existence, because it operates using real uid/gid rather than effective to determine accessibility; this matters for the non-final path components. instead, use stat. failure of stat is success if only the final component is missing (ENOENT) and otherwise is failure.
2013-08-02remove (no longer useful) namespace-protected __mktemp symbolRich Felker1-4/+1
2013-02-20use memcmp instead of str[n]cmp for temp function XXXXXX checkingRich Felker1-1/+1
2013-02-20remove leftover unused variable in mktemp after refactoringRich Felker1-1/+0
2013-02-20add mkostemp, mkstemps, and mkostemps functions and reorganize temp internalsRich Felker1-10/+4
based on patch contributed by Anthony G. Basile (blueness) some issues remain with the filename generation algorithm and other small bugs, but this patch has been sitting around long enough that I feel it's best to get it committed and then work out any remaining issues.
2011-07-28remove ugly prng from mk*temp and just re-poll time on retryRich Felker1-6/+5
2011-07-28eliminate mk*temp dependency on snprintfRich Felker1-3/+4
this helps some tiny programs be even more tiny, and barly increases code size even if both are used.
2011-06-12another return value fix for mktemp...Rich Felker1-1/+2
2011-02-19make mktemp match the historic behavior, and update functions that use itRich Felker1-1/+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.
2011-02-18major improvements to temp file name generatorRich Felker1-13/+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.
2011-02-14ensure standard functions mk[sd]temp don't depend on removed function mktempRich Felker1-1/+3
2011-02-12initial check-in, version 0.5.0v0.5.0Rich Felker1-0/+29
