status_t Datastream::SetBlocking ( bool  bBlocking = true )

Description

Set the blocking mode of the Socket associated with the Datastream. If the Socket is blocking then I/O methods such as Read() and Write() will not return until either data arrives or the operation times out. If the Socket is non-blocking then these operations will return imediatly if no data is available.

Parameters

bBlocking

false Make the Socket non-blocking, true makes the Socket blocking. Default is true.

Returns

0 on success.
