Имя (Name)

mkdtemp - create a unique temporary directory

---

Синопсис (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

Описание (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.

---

Возвращаемое значение (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 to indicate the error.

---

Ошибки (Error)

EINVAL The last six characters of template were not XXXXXX.  Now
              template is unchanged.

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

Версии (Versions)

Available since glibc 2.1.91.
