       mktemp - make a unique filename (LEGACY)

       #include <stdlib.h>

       char *mktemp(char *template);

       The mktemp() function shall replace the contents of the string pointed to by template by a
       unique filename and return template. The application shall initialize  template	to  be	a
       filename with six trailing 'X' s; mktemp() shall replace each 'X' with a single byte char-
       acter from the portable filename character set.

       The mktemp() function shall return the pointer template.  If a unique name cannot be  cre-
       ated, template shall point to a null string.

       No errors are defined.

       The following sections are informative.

   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);

       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.


       This function may be withdrawn in a future version.
