Hi Gs, Two weeks ago, I asked for links to Winsock programming tutorials. I got several responses, and I checked them out. These are the ones I currently found really helpful: http://www.ecst.csuchico.edu/~beej/guide/net/ http://www.hal-pc.org/~johnnie2/winsock.html The other links I got a still very relevant. I have learnt that there is also UNIX network programming, and that network programming isn't as daunting as I thought it was. Thanks guys for the help.

Ruppel" To: Dev-C Mailing List Subject: [Dev-C++] Access Violation (Segmentation Fault) When I debug this program, I get "Warning: An Access Violation (Segmentation Fault) raised in your program." When I get this error msg, I end up in stl_construct.h. ---------------------------------------------------------------------------------------------------------------------------- int Range=0; int PreviousRange=0; vector Groupset; // subscripts/pointers to Groupset ranges ofstream DGroupset("W:\\AAAnalysis\\DGroupset.txt"); ofstream DWDRlist("W:\\AAAnalysis\\DWDRlist.txt"); .... int main() { .... if (Mtglist[i].substr(0,1) == "*") { if (Mtglist[i].size() == 8) { Groupset.push_back(Range); <=======================> Here's the stmt that yields the error. DGroupset << Range << endl; DWDRlist << Mtglist[i] << endl; PreviousRange=Range; TWDR++; } } ----------------------------------------------------------------------------------------------------------------------------- I know that you always want to see the entire program, but it is over 300 lines long, so please let's see if anyone can see anything glaringly wrong with this, okay? At the moment of error, Range = a valid integer. DGroupset is merely a disk image of the vector so I can see what's going on. I have checked if "Range" is a reserved word (it is not). I have checked if a vector needs any special handling (it does not). I have chkdsk'ed the partition. What could cause this? What are some causes a Segmentation Fault?

What changes is how you compile the program. Instead of adding WS2_32.LIB/WSOCK32.LIB you add -lws2_32/-lwsock32 to your linker command line. The includes, structures & functions all stay the same (the libraries also stay the same but they have slightly different file names) Ehi Ikhimiukor wrote: > Hi guys, > Can someone please tell me how to do WinSock programming with Dev C++?

One thing you should note is that programming winsock is UNIX network programming with some extra Microsoft specific additives. The BSD socket interface (UNIX network programming interface) existed long before Microsoft created winsock, the kick is winsock was designed using the BSD interface as it's basis.
