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 tem
- plate 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.
