How to use sys/socket.h functions in windows OS.

[Ravikumar]

Hi All,

The following code snippet is a part of s/w which is downloaded from
net. While compiling this code I got the following error.

...\..\snmplib\snmpTCPDomain.c(6) : fatal error C1083: Cannot open
include file: 'sys/socket.h': No such file or directory
NMAKE : fatal error U1077: 'cl.exe' : return code '0x2'
Stop.
NMAKE : fatal error U1077: 'C:\PROGRA~1\MICROS~3\VC98\BIN\NMAKE.EXE' :
return code '0x2'
Stop.

I just looked into the code and I found out that the problem is raised
because of sys/socket.h file. So please help me as how to use the
sys/socket.h file in windows OS . I am working on Windows OS. Hence I
am facing the problem.


Please help me as How to resolev this issue . Your thoughts will be
highly appreciated.

Thanks in Advance.

Thanks

This is a question better asked in another newsgroup, take a look here

This is Unix/Linux code (sys/socket.h). You can not
use that in MS Windows. You must include the Windows
socket header instead, and possibly modify the rest of
the program to call Windows socket API's instead of
Unix socket API's.

Ask for further help in a Microsoft Windows/Visual C newsgroup.
