Function
The SktTCPConnect instruction requests a connection between local TCP port number SrcTcpPort and
destination TCP port number DstTcpPort at destination address DstAdr. To do this, it executes the Con-
nect() socket function. The connection is established when the instruction is completed normally (i.e.,
when the value of Done changes to TRUE).
The data type of Socket is structure _sSOCKET. The specifications are as follows:
