NAMEmkdtemp - create a unique temporary directory
#include <stdlib.h> char *mkdtemp(char *template);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
DESCRIPTIONThe 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 VALUEThe mkdtemp() function returns a pointer to the modified template string on success, and NULL on failure, in which case errno is set appropriately.
- The last six characters of template were not XXXXXX. Now template is unchanged.
Also see mkdir(2) for other possible values for errno.
VERSIONSAvailable since glibc 2.1.91.
CONFORMING TOPOSIX.1-2008. This function is present on the BSDs.
