Pascal

function SendTo(
    ASocket: TIdStackSocketHandle; 
    const ABuffer: TIdBytes; 
    const AOffset: Integer; 
    const AIP: string; 
    const APort: integer; 
    const AIPVersion: TIdIPVersion = ID_DEFAULT_IP_VERSION
): Integer; virtual; abstract;

Parameters

Parameters	Description
ASocket	Socket handle for the operation.
ABuffer	Values to be sent on the socket handle.
AOffset	Offset into the buffer to locate values to send.
AIP	IP address for the remote destination.
APort	Port number for the remote destination.
AIPVersion	IP address family for the IP address.

Returns

Integer - Number of bytes written to the socket handle.

Description

SendTo is an abstract virtual Integer function that specifes the method used to access the SendTo() API for a protocol stack implementation.

SendTo is used to write the outgoing data in ABuffer on the socket handle in ASocket. SendTo uses the IP address and port numer in AIP and APort as the destination for the transmission.

SendTo is normally used on a datagram socket, but can also override the current remote network destination for a streaming socket.

Use Send to transmit data using a specified socket after the connection to the remote system has been established.
