Not quite what you ask for, but I found this code snippet lying about... can't vouch for its correctness (let alone portability - looks like 32-bit only): // detect computer architecture union {double f; uint32 i[2];} etest; etest.f = 1.0; if (etest.i[1] == 0x3FF00000) Architecture = LITTLEENDIAN; else if (etest.i[0] == 0x3FF00000) Architecture = BIGENDIAN; else Architecture = NONIEEE; Regards, Lionel
