NAME¶
mkdtemp - create a unique temporary directorySYNOPSIS¶
#include <stdlib.h>char *mkdtemp(char *template);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
_BSD_SOURCE
|| /* Since glibc 2.10: */
(_POSIX_C_SOURCE >= 200809L ||
_XOPEN_SOURCE >= 700)
DESCRIPTION¶
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.RETURN VALUE¶
The mkdtemp() function returns a pointer to the modified template string on success, and NULL on failure, in which case errno is set appropriately.ERRORS¶
- EINVAL
- The last six characters of template were not XXXXXX. Now template is unchanged.
