Syntax

virtual bool RecvFromWithPktInfo
(
    uint8 * Data,
    int32 BufferSize,
    int32 & BytesRead,
    FInternetAddr & Source,
    FInternetAddr & Destination,
    ESocketReceiveFlags::Type Flags
)

Remarks

Reads a chunk of data from the socket and gathers the source address and the destination using IP_PKTINFO

A return value of 'true' does not necessarily mean that data was returned. Callers must check the 'BytesRead' parameter for the actual amount of data returned. A value of zero indicates that there was no data available for reading.

Returns

true on success, false in case of a closed socket or an unrecoverable error.

Parameters

Parameter	Description
Data	The buffer to read into.
BufferSize	The max size of the buffer.
BytesRead	Will indicate how many bytes were read from the socket.
Source	Will contain the receiving the address of the sender of the data.
Destination	Will contain the destination address used by the sender of the data.
Flags	The receive flags.
