Dear Experts, I'm trying to port a simple UDP application, which ran on Linux and Symbian, to Windows Mobile 6.5. I was going to do a fresh MSVC project, but then ran into cegcc, and gave it a try. I have to say, cegcc saves me a lot of efforts. However, I ran into an issue with missing UDP packets, details are given below.
I use arm-ming32ce on Linux, and have revised my code to get it compiled. More specifically, I commented out a few BSD socket headers, and add the following includes: #define __USE_WIN32_SOCKETS #include<winsock.h> #include<windows.h> #include<string.h> #include<process.h> #include<stdio.h> I link the object files using the options: -static -static-libgcc -lws2 My application uses sendto() and recvfrom() to communicate with multiple UDP servers over WiFi. And I can see some UDP packets showing up at the server side using wireshark. However, I have noticed that many packets are not actually sent even though sendto() returns a nonzero value. Similar thing happens to recvfrom(): most of the time I receive only one or two incoming UDP packets. I wonder whether I made any newbie mistakes? Please advise, and thanks in advance.
