+@deftypefn Supplemental char* tmpnam (char *@var{s})
+
+This function attempts to create a name for a temporary file, which
+will be a valid file name yet not exist when @code{tmpnam} checks for
+it.  @var{s} must point to a buffer of at least @code{L_tmpnam} bytes,
+or be @code{NULL}.  Use of this function creates a security risk, and it must
+not be used in new projects.  Use @code{mkstemp} instead.
