 Variant 1: 
	
 NET_API_STATUS x=NetMessageBufferSend ( 
                 LPTSTR servername, 
         LPTSTR msgname, 
         LPTSTR fromname, 
         LPTSTR buf, 
         DWORD buflen 
           );

 Variant 2: 

From: "Alexandr Shandra" <entryway@astral.ntu-kpi.kiev.ua> 

It is possible through CreateFile/WriteFile, but in this case it is possible to send the message 
Only to the computer or on local working group. 

Here an example: (works both under NT and under 9x); 

HANDLE hSlot = CreateFile ("\\\\computername \\mailslot \\messngr", 
    GENERIC_WRITE, FILE_SHARE_READ, NULL, 
    OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL); 

if (hSlot! = INVALID_HANDLE_VALUE) 
{ 
   char buf = "From\0\To\0Message\0"; 
   uint cb = sizeof (buf); 
   WriteFile (hSlot, buf, cb, &cb, NULL); 
   CloseHandle (hSlot); 
}
