NAME

       explain_mkdtemp_or_die - create a unique temporary directory and report errors

SYNOPSIS

       #include <libexplain/mkdtemp.h>
       char *explain_mkdtemp_or_die(char *pathname);
       char *explain_mkdtemp_on_error(char *pathname);

DESCRIPTION

       The  explain_mkdtemp_or_die  function  is  used	to  call  the mkdtemp(3) system call. On failure an explanation will be printed to stderr,
       obtained from the explain_mkdtemp(3) function, and then the process terminates by calling exit(EXIT_FAILURE).

       The explain_mkdtemp_on_error function is used to call the mkdtemp(3) system call. On failure an explanation  will  be  printed  to  stderr,
       obtained from the explain_mkdtemp(3) function, but still returns to the caller.

       pathname
	       The pathname, exactly as to be passed to the mkdtemp(3) system call.

RETURN VALUE

       The  explain_mkdtemp_or_die  function  only  returns on success, see mkdtemp(3) for more information. On failure, prints an explanation and
       exits, it does not return.

       The explain_mkdtemp_on_error function always returns the value return by the wrapped mkdtemp(3) system call.

EXAMPLE

       The explain_mkdtemp_or_die function is intended to be used in a fashion similar to the following example:
	      char *result = explain_mkdtemp_or_die(pathname);

SEE ALSO

       mkdtemp(3)
	       create a unique temporary directory

       explain_mkdtemp(3)
	       explain mkdtemp(3) errors

       exit(2) terminate the calling process

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 appro-
       priately.

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.
