sack::network::tcp::doReadExx Function

C++

IMPORT_METHOD size_t doReadExx(PCLIENT lpClient, POINTER lpBuffer, size_t nBytes, LOGICAL bIsStream, LOGICAL bWait);

File

network.h

Parameters

Parameters	Description
PCLIENT lpClient	network client to read from
POINTER lpBuffer	buffer to read into
size_t nBytes	size of the buffer to read or maximum amount of the read desired.
LOGICAL bIsStream	if TRUE, any opportunity to return a packet is used to pass data to the user's read callback. If FALSE, will read to the complete size nBytes specified.
LOGICAL bWait	if TRUE, will block in the read until there is data, or the buffer is filled completely depending on the value of bIsStream. If FALSE, returns immediately, the read completion will be notified later by callback.

Returns

size of the packet read if bWait is TRUE,

else TRUE for sent, FALSE if the packet could not be sent.

This buffer needs to continue existing until the socket is closed, or the read callback returns.

Description

Example

Used in a normal read callback...

void CPROC ReadComplete( PCLIENT pc, POINTER buffer, int size )
{
    if( buffer == NULL )
        buffer = malloc( 4096 );
    else
    {
       // size will be non 0, process buffer
    }
    ReadTCP( pc, buffer, 4096 );
}
