mktemp(3C)                                             mktemp(3C)



NAME
     mktemp - makes a unique filename

SYNOPSIS
     char *mktemp(template)
     char *template;

DESCRIPTION
     The function mktemp alters the contents of the string
     referenced by *template so that it becomes a unique
     filename.  The string at *template should be initialized to
     a filename 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 does not duplicate an
     existing file.

STATUS MESSAGES AND VALUES
     The mktemp program returns the address of the unique
     (altered) filename.  If a unique name cannot be created,
     template will point to a null (empty) string.

LIMITATIONS
     It is possible to run out of letters.
