mkdtemp - create a unique temporary directory
#include <stdlib.h> char * mkdtemp (char * template);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
/* Since glibc 2.19: */ _DEFAULT_SOURCE || /* Glibc 2.19 and earlier: */ _BSD_SOURCE || /* Since glibc 2.10: */ _POSIX_C_SOURCE >= 200809L
The mkdtemp() function generates a uniquely named temporary directory from
template. The last six characters of
template must be XXXXXX and these are replaced with a string that makes the directory name unique. The directory is then created with permissions 0700. Since it will be modified,
template must not be a string constant, but should be declared as a character array.
The mkdtemp() function returns a pointer to the modified template string on success, and NULL on failure, in which case
errno is set appropriately.
The last six characters of
template were not XXXXXX. Now
template is unchanged.
Also see mkdir(2) for other possible values for
Available since glibc 2.1.91.
