MKDTEMP(3) Linux Programmer's Manual MKDTEMP(3)NAMEmkdtemp - create a unique temporary directory
char *mkdtemp(char *template);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
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
EINVAL The last six characters of template were not XXXXXX. Now tem‐
plate is unchanged.
Also see mkdir(2) for other possible values for errno.
Available since glibc 2.1.91.
POSIX.1-2008. This function is present on the BSDs.
