// The ParseHostPort function parses a VNC host name which can be specified
|
|
// in one of these formats:
|
|
// (1) hostname
|
|
// (2) hostname:display (display < 100)
|
|
// (3) hostname:port (port >= 100)
|
|
// (4) hostname::port
|
|
// The function determines and returns the port number, and modifies str[]
|
|
// by inserting a zero byte in place of the first colon found in the string.
|
|
// The algorithm of determining the port number is as follows:
|
|
// (1) if there are no colons in the string, base_port is used;
|
|
// (2) if there is one colon and the following number is less than 100,
|
|
// then the port number is calculated by adding this number (display
|
|
// number) to base_port;
|
|
// (3) if there is one colon and the following number is 100 or greater,
|
|
// then this number is interpreted as a port number;
|
|
// (4) if there are two colons, the following number is always treated as
|
|
// a port number.
