mktemp



PURPOSE

Constructs a unique file name.

LIBRARY

Standard C Library (libc.a)

SYNTAX

char *mktemp (template)
char *template;

DESCRIPTION

The mktemp subroutine replaces the contents of the string pointed to by the
template parameter with a unique file name.

The string in the template parameter must be a file name with six trailing
"X"s.  The mktemp subroutine replaces the "X"s with a character sequence such
that the string pointed to by template is a filename which does not name an
existing file.

Upon successful completion, the mktemp subroutine returns the address of the
string pointed to by the template parameter.

If mktemp is unable to construct a unique file name from the template, then the
first character of the template string is replaced with a null character, and a
NULL pointer is returned.
