.SH DESCRIPCIÓN
\fINever use this function\fP; see BUGS.
.PP
The \fBmktemp\fP()  function generates a unique temporary filename from
\fItemplate\fP.  The last six characters of \fItemplate\fP must be XXXXXX and
these are replaced with a string that makes the filename unique.  Since it
will be modified, \fItemplate\fP must not be a string constant, but should be
declared as a character array.
.SH "VALOR DEVUELTO"
The \fBmktemp\fP()  function always returns \fItemplate\fP.  If a unique name was
created, the last six bytes of \fItemplate\fP will have been modified in such a
way that the resulting name is unique (i.e., does not exist already)  If a
unique name could not be created, \fItemplate\fP is made an empty string, and
\fIerrno\fP is set to indicate the error.

.SH ESTÁNDARES
.\" .SH NOTES
.\" The prototype is in
.\" .I <unistd.h>
.\" for libc4, libc5, glibc1; glibc2 follows the Single UNIX Specification
.\" and has the prototype in
.\" .IR <stdlib.h> .
4.3BSD, POSIX.1\-2001.  POSIX.1\-2008 removes the specification of
\fBmktemp\fP().
.SH ERRORES
Never use \fBmktemp\fP().  Some implementations follow 4.3BSD and replace
XXXXXX by the current process ID and a single letter, so that at most 26
different names can be returned.  Since on the one hand the names are easy
to guess, and on the other hand there is a race between testing whether the
name exists and opening the file, every use of \fBmktemp\fP()  is a security
risk.  The race is avoided by \fBmkstemp\fP(3)  and \fBmkdtemp\fP(3).
