2013-02-20use memcmp instead of str[n]cmp for temp function XXXXXX checkingRich Felker2-2/+2
2013-02-20fix error cases in mkostemps coreRich Felker1-6/+3
1. wrong return value and missing errno for negative suffix len 2. failure to catch suffix len > strlen 3. remove unwanted clearing of input string in invalid case
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 Felker6-29/+83
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 Felker3-5/+8
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.
2011-02-19fix major bug created from copying mkdtemp logicRich Felker1-1/+1
2011-02-18major improvements to temp file name generatorRich Felker3-16/+21
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.
2011-02-18reformat mkstemp like mkdtempRich Felker1-7/+5
this is cleaner and makes it easy to impose a limit on the number of retries later if it seems desirable to do so.
2011-02-14ensure standard functions mk[sd]temp don't depend on removed function mktempRich Felker3-5/+9
2011-02-14begin namespace-cleanup of standard C headersRich Felker2-0/+2
2011-02-12initial check-in, version 0.5.0v0.5.0Rich Felker3-0/+76
