If you need this at run-time, the ofvious way is to check, if sizeof(long) or whatever provides the bytecount of a LP64/ILP32 programming model. If the information is needed at compile-time, check unistd.h, were _XBS_LP64_OFF64 is set. The relevant includes are: bits/posix_opt.h, bits/environments.h and bits/wordsize.h The selection, which programming model is used, is controlled there in a fairly detailed manner, which has the advantage of being "The POSIX Way(TM)", and therefore even portable outside the Linux world ( can anybody with access to a True64 System check this claim ? I would be interested... ) Depending on what specific aspects of the machine's wordsize you need, you can go as straight as checking if __WORDSIZE is set to 32 or 64, or as controlled as checking if _XBS5_LP64_OFF64 provides a 64-bit pointer environment. Have a look at the include-files i named above. I doubt, you'll find a situation not being covered there ;-) > Thanks in advance > Adrian Regards, Thomas -- Thomas Weyergraf [EMAIL PROTECTED] My Favorite IA64 Opcode-guess ( see arch/ia64/lib/memset.S ) "br.ret.spnt.few" - got back from getting beer, did not spend a lot.
