| Net.TokenAvailable | Part of Net module |
| Syntax | Net.TokenAvailable (netStream : int) : boolean
|
| Description | Returns true if a line of input is waiting to be read from the net stream specified by the netStream parameter. If Net.TokenAvailable returns true, then a single token (character surrounded by whitespace) can be read from the stream without blocking.
|
| Details | The Net module requires a TCP/IP stack to be installed and operating in order to function. It does not communicate using any other protocols It is possible for Firewalls to interfere with the actions of the Net module, preventing connections from taking place.
|
| Example | The following program fragment reads a character from netStream only if there is one waiting to be read.
if Net.TokenAvailable (netStream) then
var token : string
get : netStream, token
put token
end if
|
| Status | Exported qualified. This means that you can only call the function by calling Net.TokenAvailable, not by calling TokenAvailable.
