valid socket ID for an open connection

Description

• 

These four procedures return information about the endpoints of a socket connection.

• 

Each routine requires a single argument, which is a valid socket ID for an open connection. Either a string or a positive integer is returned, depending upon the type of information requested.

• 

The procedure GetLocalHost returns the hostname of the local endpoint in a socket connection, while GetPeerHost returns the hostname of the peer side of the connection. In each case, the hostname is returned in the form of a string.

  

Port numbers for the local and remote endpoints are obtained as positive Maple integers by using the routines GetLocalPort and GetPeerPort, respectively.
