[forum] Fwd: Hooking

[ramalingareddy bommalapura]

 Hi All,
          Can anybody please suggest how hooking can be done
in the xserver functions. XServer needs to invoke my function before
the call is passed to the XServer original function. I have found that
this is the procedure in windows for doing hooking:

HOOKPROC hkprcSysMsg; 
static HINSTANCE hinstDLL; 
static HHOOK hhookSysMsg; 
 
hinstDLL = LoadLibrary((LPCTSTR) "c:\\windows\\sysmsg.dll"); 
hkprcSysMsg = (HOOKPROC)GetProcAddress(hinstDLL, "SysMessageProc"); 
hhookSysMsg = SetWindowsHookEx(WH_SYSMSGFILTER,hkprcSysMsg,hinstDLL,0); 

Please suggest a function similar to SetWindowsHookEx in Linux or else suggest 
some procedure in which I can do the hooking in linux.

Any help in this regard will be greatly appreciated,

Thank you.

Best Regards
Rama
