{{PageDescription}}
|
|
* Creates an [[ERROR Codes|Illegal Function Call]] error if called with a string argument of the wrong syntax.
|
|
* The port used in the syntax example is 8080.
|
|
* Valid {{Parameter|hostHandle}} values are negative numbers.
|
|
* If the syntax is correct but they fail to begin/connect a {{Parameter|hostHandle}} of 0 is returned.
|
|
* Always check if the handle returned is 0 (failed) before continuing.
|
|
* [[CLOSE]] {{Parameter|hostHandle}} closes the host. A failed handle value of 0 does not need to be closed.
