I would like to use the offsetof() macro in the implementation of the revised metafile I/O routines. My goal is to define the data file format in a variable and to support multiple versions for backwards compatibility.
Our actual minimum supported C version is C99 (since we already use some C language constructs that were first introduced for C99). According to the Linux man page offsetof is CONFORMING TO C89, C99, POSIX.1-2001. Therefore, using that macro should be fine since it would be a pretty lame C compiler that didn't support C99, 14 years after the fact. Alan __________________________ Alan W.
