I find this kind of strange but when I use the FD_SET macro in my program everything compiles fine but when I run the executable it crashes.
Any suggestions why this happens ?Code:SOCKET test; fd_set read_check; FD_SET(test, &read_check);
EDIT: I'm using the mingw c/c++ compilers and Code::Blocks.
Did you initialise the socket variable test?
Did you FD_ZERO the set before using it?
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
I thought I did, but when I created a new project just for testing it all worked perfectly. The trouble is in a socket class I'm writing so I have to double check the class code it seems.
If it wasn't for your reply I would not have checked this because I was absolutely sertain I had initialized the socket and also FD_ZERO the set. Thank you!
