MKDTEMP(3) Linux Programmer's Manual MKDTEMP(3)
mkdtemp - create a unique temporary directory
#include <stdlib.h>
char *mkdtemp(char *template);
Feature Test Macro Requirements for glibc (see
feature_test_macros(7)):
mkdtemp():
/* 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.
EINVAL The last six characters of template were not XXXXXX. Now
template is unchanged.
Also see mkdir(2) for other possible values for errno.
Available since glibc 2.1.91.
For an explanation of the terms used in this section, see
attributes(7).
