mktemp(3C)                                             mktemp(3C)



     NAME
          mktemp - make a unique filename

     SYNOPSIS
          char *mktemp(template)
          char *template;

     DESCRIPTION
          The function mktemp alters the contents of the string refer-
          enced by *template so that it becomes a unique filename.
          The string at *template should be initialized to a filenamed
          with six trailing X characters; mktemp replaces the Xs with
          a letter and the current process ID.  The letter is selected
          so that the resulting name is not a duplicate an existing
          file.

     RETURN VALUE
          mktemp returns the address of the unique (altered) filename.
          If a unique name cannot be created, template will point to a
          null (empty) string.

     BUGS
          It is possible to run out of letters.
