Return Values

[webstony]

Hello everybody,

once more I need your help!

My little program should be compatible to UNIX and WINDOWS environments. In Windows I can retrieve the error code if send() or receive() function of winsock fails with WSAGetLastError(). How can I retrieve the error code under UNIX environments?

Thanks a lot,
cu, Stony

In most unix environments, the global variable errno holds the last error code. Be careful of this in threaded code though!
