/*! <pre>
|
||
|
|
Commandline interface that allows applications to communicate over pipe || socket || serial line || stdio .
|
||
|
|
|
||
|
|
The parameters of start() are as follows:
|
||
|
|
start("stdio"); // use stdin and stdout
|
||
|
|
start("pipe","command"); // run "command" and connect it's stdio with us (runs on unix only)
|
||
|
|
start("host:5050"); // connect to "host" on port 5050 and communicate with the server (tip: define a server with xinted on "host" port 5050)
|
||
|
|
start("localhost:5050","command"); // run "command" and then try to connect to "localhost" port 5050 for communication with "command"
|
||
|
|
start("server.localhost:5050"); // act as a server on "localhost" port 5050 (can serve only 1 client. if you want to serve more clients use rlSocket)
|
||
|
|
start(tty); // use serial interface for communication
|
||
|
|
|
||
|
|
Return values:
|
||
|
|
start() returns -1 on error
|
||
|
|
readLine() returns the read string or NULL
|
||
|
|
readBlock() returns the number of read bytes or -1 on error
|
||
|
|
printf() returns the number of written characters or -1 on error
|
||
|
|
writeBlock() returns the number of written bytes or -1 on error
