mktemp(3C)						   Standard C Library Functions 						mktemp(3C)

NAME
mktemp - make a unique file name from a template SYNOPSIS
#include <stdlib.h> char *mktemp(char *template); DESCRIPTION
The mktemp() function replaces the contents of the string pointed to by template with a unique file name, and returns template. The string in template should look like a file name with six trailing 'X's; mktemp() will replace the 'X's with a character string that can be used to create a unique file name. Only 26 unique file names per thread can be created for each unique template. RETURN VALUES
The mktemp() function returns the pointer template. If a unique name cannot be created, template points to a null string. ERRORS
No errors are defined. EXAMPLES
Example 1 Generate 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); 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(3C) function avoids this problem and is preferred over this function. ATTRIBUTES
