The [_OPENHOST](_OPENHOST) function opens a Host which listens for new connections and returns a Host status handle.
|
||
|
|
||
|
## Syntax
|
||
|
|
||
|
> hostHandle = [_OPENHOST](_OPENHOST)(**"TCP/IP:8080"**)
|
||
|
|
||
|
## Description
|
||
|
|
||
|
* Creates an [ERROR Codes](ERROR-Codes) error if called with a string argument of the wrong syntax.
|
||
|
* The port used in the syntax example is 8080.
|
||
|
* Valid hostHandle values are negative numbers.
|
||
|
* If the syntax is correct but they fail to begin/connect a hostHandle of 0 is returned.
|
||
|
* Always check if the handle returned is 0 (failed) before continuing.
|
||
|
* [CLOSE](CLOSE) hostHandle closes the host. A failed handle value of 0 does not need to be closed.
