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

NAME         top

       mkdtemp - create a unique temporary directory

SYNOPSIS         top

       #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

DESCRIPTION         top

       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         top

       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         top

       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         top

       Available since glibc 2.1.91.
