.SH DESCRIPTION
.I Mktemp
replaces
.I template
by a unique file name, and returns the
address of the template.
The template should look like a file name with eleven trailing
.LR X s.
The
.LR X s
are replaced by a letter followed by the current process id.
Letters from
.L a
to
.L z
are tried until a name that can be accessed
(see
.IR access (2))
is generated.
If no such name can be generated,
.I mktemp
returns
\f5"/"\f1 .
