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():
           /* Since glibc 2.19: */ _DEFAULT_SOURCE
           || /* Glibc 2.19 and earlier: */ _BSD_SOURCE
           || /* Since glibc 2.10: */ _POSIX_C_SOURCE >= 200809L

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.
