Description :

This function sets various parameters and modes for sessions, as well as preallocating a network buffer. If this function is called more than once (for a given session), the previous allocated buffer is deallocated and a new one allocated. This means that any bytes being buffered for sends or receives are lost.

SendTimeout - Default send timeout (10 ms. units).

NumBuffers - Number of network buffers to preallocate.

BufferSize - Default buffer size (0 indicates use a driver selected size).

Output : (routine) - Return status from this call -- indicates either success or what the error is. The return codes include:

NOERROR - Function returned successfully. ERR_xxx - STATUS returned from a lower-level C API function. This value can be passed to OSLoadString to obtain a text string for the error. This error should be treated as fatal and the session should be closed by the application via NetCloseSession.
