Under *nix socket calls are just general runtime calls, and they use the same convention and constants for errorhandling as all other calls.
As I know "nothing" about Linux, then it is safe to check?: socket := Sockets.FPSocket(...); if socket = -1 then // invalid socket returned due to error ...
This technique is used in fcl-net which should be cross-platform. So I am right, when I say that also in Linux invald socket = -1 (in other words: in case of error syscall() returns always -1) Becuase in other place I see another test "if socket < 0 then ..." (which may mean that any negative value can be returned) L. _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
