RE: [Dev-C++] Get socket with socket function

But your application will be dependent on the Cygwin DLLs, which can be a
nuisance. I always prefer native code over emulation, especially when the
emulation requires 3rd party libraries.

If you configure Dev-C++ to use cygwin as the build env you will not have to
change your code.

	Hi all, 


	I managed to compile a simple program that should just wait for an
icoming connection on a inet type socket. I did it under Mac OS X and Linux,
and I want to do the same thing with dev-cpp. 


	Due to explanation give on this mailing list (thanks for your quick
and usefull answers), I change the code to use winsock.h instead of
sys/socket.h. I added the necessary library and DLLs. The program starts
correctly and get it the function to create the socket file descriptor (it
is very simple) : 


	int sockfd; 


	sockfd = socket(AF_INET, SOCK_STREAM, 0); 


	BUT the result of socket function is always -1 (sockfd = -1). What
could be the cause of that ? I found a similar example of socket creation
for windows, I did exactly the same as in the example. The only thing I have
found in "socket" man page is : 


	"A -1 is returned if an error occurs" 


	But how can an error happen at this step ? 


	Thank you for any advice. 


	Best regards.
