I have a problem to retrieve th hostname of my pc.
I'm using Windows XP SP2 with the last updates and GNU Dev C++ 4.9.9.2.
Here my little test program:

#include <winsock2.h>
#include <unistd.h>
int main(void) {
char host_name[255] = {0};
int ccode;
if (( ccode = gethostname( host_name, sizeof( host_name))) != 0) {
printf( "gethostname failed, ccode = %d\n", ccode);
return EXIT_FAILURE;
}
printf( "host name: %s\n", host_name);
return EXIT_SUCCESS;

}

Used Libraries:
"../../Compiler lcc-win32/lcc/lib/ws2_32.lib"
"../../Compiler lcc-win32/lcc/lib/kernel32.lib"
"../../Compiler lcc-win32/lcc/lib/user32.lib"

Linking makes no problems. But when executing I get the message
the entry point `FindAtomA' could not be found in the dll `WS2_32.DLL'.


What am I doing wrong?

You are asking the question in the wrong newsgroup. Your problem seems
to be 100% windows related, and clc only discusses ANSI-C. Please go to
the proper comp.windows.* group and ask again.


Thank you.

You are using the lcc-win32 libraries but do you use the
lcc-win32 compiler?

GNU Dev C++ is NOT the lcc-win32 compiler. Please do
not mix compilers because it will lead to failures.

Thank you very much. I didn't recognize that.
There are so a lot of libs in the GNU Dev-CPP directories. Is there
anywhere a list to find out what they are for? Or do you know which one
I have to include?

This discussion is off-topic in comp.lang.c++ and, I suspect, in
comp.lang.c. Followup set to gnu.g++.help (please respect it).

File closed. I used the lcc-win libraries instead of the GCC ones.
Sorry but I'm just beginning with C.
