-Generate a unique temporary file name from @var{pattern}.
-@var{pattern} 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{pattern} 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.
