NAME
mktemp - make a unique file name
SYNOPSIS
char *mktemp(template) char *template; mkstemp(template) char *template;
DESCRIPTION
Mktemp creates a unique file name, typically in a temporary filesystem,
by replacing
template with a unique file name, and returns the
address of the template.
The template should contain a file name with six trailing
X's, which are replaced with the
current process id and a unique letter.
Mkstemp makes the same replacement to the template
but returns a file descriptor
for the template file open for reading and writing.
Mkstemp avoids the race between testing whether the
file exists and opening it for use.

getpid(2), open(2)
DIAGNOSTICS
Mkstemp returns an open file descriptor upon success.
It returns -1 if no suitable file could be created.
