Afaik most is in the docs, but some short pointers: 32 64 unsigned 16 bits WORD? WORD? signed 16 bits see table docs (smallint/shortint) unsigned 32 bits DWORD? DWORD? signed 32 bits compiler mode dependant 16/32 unsigned 64 bits QWORD? QWORD? signed 64 bits Int64? Int64? Native "integer" "native" is ambiguous. Signed integer as big as pointer PtrInt Ptrint Unsigned integer as big as pointer PtruInt Ptruint "native" is confusing since it can taken in many ways. Native as in most performance? Register size? Addressing size? Addressing size + segment ? (size_t, ssize_t). > Where LongInt fits ? Bits dependent or not ? always 32-bit signed. > Maybe a table is available in the wiki, but I was unable to find it. The docs are the primary source, the language ref should have a table somewhere near the start. I sometimes use it, because I always forget which is 8-bit signed and which is 16-bit signed. (which is why I never use them and always use ctypes) _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
