@deftypefn Replacement int mkstemps (char *@var{template}, int @var{suffix_len})
Generate a unique temporary file name from @var{template}.
@var{template} has the form:
@example
@var{path}/ccXXXXXX@var{suffix}
@end example
@var{suffix_len} tells us how long @var{suffix} is (it can be zero
length). The last six characters of @var{template} before @var{suffix}
must be @samp{XXXXXX}; they are replaced with a string that makes the
filename unique. Returns a file descriptor open on the file for
reading and writing.
