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  cre-
       ate  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 file-
       name.

       #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  pos-
       sible  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.
