Hi Gambit List, What's the simplest way to append 32bit unsigned integers to a file in gambit? (not bothered about maintaining endian portability or anything) I'm currently using a C hack (see below), but it feels like there ought to be something less clunky. Thanks, Phil (c-declare "#include <stdio.h>") (define fopen (c-lambda (nonnull-char-string nonnull-char-string) (pointer "FILE") "fopen")) (define fclose (c-lambda ((pointer "FILE")) int32 "fclose")) (define write-u32vector-to-file ; args: port, u32-vector, len (c-lambda ((pointer "FILE") scheme-object unsigned-int32) int32 "___result = fwrite((void*)(___BODY_AS(___arg2,___tSUBTYPED)), 4, ___arg3, ___arg1);")) (define read-u32vector-from-file ; args: port, u32-vector, len (c-lambda ((pointer "FILE") scheme-object unsigned-int32) int32 "___result = fread((void*)(___BODY_AS(___arg2,___tSUBTYPED)), 4, ___arg3, ___arg1);"))
