LEARN ABOUT POSIX
mktemp
MKTEMP(P) POSIX Programmer's Manual MKTEMP(P)
NAME
mktemp - make a unique filename (LEGACY)
SYNOPSIS
#include <stdlib.h>
char *mktemp(char *template);
DESCRIPTION
The mktemp() function shall replace the contents of the string pointed to by template by a unique filename and return template. The appli-
cation shall initialize template to be a filename with six trailing 'X' s; mktemp() shall replace each 'X' with a single byte character
from the portable filename character set.
RETURN VALUE
The mktemp() function shall return the pointer template. If a unique name cannot be created, template shall point to a null string.
ERRORS
No errors are defined.
The following sections are informative.
EXAMPLES
Generating a Filename
The following example replaces the contents of the "template" string with a 10-character filename beginning with the characters "file" and
returns a pointer to the "template" string that contains the new filename.
#include <stdlib.h>
...
char *template = "/tmp/fileXXXXXX";
char *ptr;
ptr = mktemp(template);
APPLICATION USAGE
Between the time a pathname is created and the file opened, it is possible for some other process to create a file with the same name. The
mkstemp() function avoids this problem and is preferred over this function.
RATIONALE
None.
FUTURE DIRECTIONS
This function may be withdrawn in a future version.
