tmpfile, tmpnam \- System V compatibility routines
.SH SYNOPSIS

.SH COMMENT
The \fI#defines\fP \fIP_tmpdir\fP and \fIL_tmpnam\fP, used by the routines
\fItempnam\fP, \fItmpfile\fP, and \fItmpnam\fP are not available in
\fI<stdio.h>\fP.  If the code requires them, just use:
.PP
#include <sys/param.h>
.br
#define	P_tmpdir	"/usr/tmp"
#define	L_tmpnam	MAXPATHLEN
.PP
Also, note that the caveat in the System V manual page that these functions
can start recycling previously used names is untrue in this system.
.SH DESCRIPTION
The above routines are available and behave as in System V.
.PP
.BR strchr ()
and
.BR strrchr ()
are simply an alternate entry points into 
.BR index ()
and
.BR rindex ()
respectively.
