* make mktemp match the historic behavior, and update functions that use itRich Felker2011-02-193-5/+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.
* fix major bug created from copying mkdtemp logicRich Felker2011-02-191-1/+1
|
* major improvements to temp file name generatorRich Felker2011-02-183-16/+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.
* reformat mkstemp like mkdtempRich Felker2011-02-181-7/+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.
* ensure standard functions mk[sd]temp don't depend on removed function mktempRich Felker2011-02-143-5/+9

* begin namespace-cleanup of standard C headersRich Felker2011-02-142-0/+2
