MKDTEMP(3)                                          Linux Programmer's Manual                                         MKDTEMP(3)



NAME
       mkdtemp - create a unique temporary directory

SYNOPSIS
       #include <stdlib.h>

       char *mkdtemp(char *template);

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

       mkdtemp(): _BSD_SOURCE

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.

       Also see mkdir(2) for other possible values for errno.

VERSIONS
       Available since glibc 2.1.91.

CONFORMING TO
       POSIX.1-2008.  This function is present on the BSDs.
