Receives data from a connected Socket.

Declaration

Parameters

• buffer - storage location for the received data.
• offset - the location in buffer to store the received data.
• size - The number of bytes to receive
• socketFlags - a bitwise combination of the SocketFlags values

Socket flags values:

[.NET] [Pascal] Value Description sfNone 1 Use no flags for this call sfOutOfBand = 2 2 Process out-of-band data sfPeek 4 Peek at incoming message sfDontRoute 8 Send without using routing tables sfMaxIOVectorLength 16 Provides a standard value for the number of WSABUF structures used to send and receive data sfTruncated 32 … sfControlDataTruncated 64 … sfBroadcast 128 … sfMulticast 256 … sfPartial 512 Partial send of receive of message

Return value

    The number of bytes received.

Description

    The Blocking parameter determines the behavior of this method when no incoming data is available. When False, a SocketException is thrown. When True, this method blocks and waits for data to arrive.
    If you specify the Peek flag as the socketFlags parameter, the available data is copied into the receive buffer but not removed from the system buffer. If you specify the OutOfBand flag as the socketFlags parameter and the Socket is configured for in-line reception of out-of-band (OOB) data (using OutOfBandInline) and OOB data is available, Receive will return only OOB data. The OOB data is a logically independent transmission channel associated with each pair of connected stream sockets. This data is delivered with higher priority and independently of the normal data.
    Please note that you should not call this method for SSLSocket class but for derived classes only.
