Syntax
registerCFunction(JSFunctionName, libraryPath,
externalFunctionName) Parameters
Description
registerCFunction is a top-level server-side JavaScript function that is not associated with any object.
Use registerCFunction to make an external function available to a server-side JavaScript application. The function can be written in any language, but you must use C calling conventions.
To use an external function in a server-side JavaScript application, register the function with registerCFunction, and then call it with the callC function. Once an application registers a function, you can call the function any number of times.
The registerCFunction function returns true if the external function is registered successfully; otherwise, it returns false. For example, registerCFunction can return false if the JavaScript runtime engine cannot find either the library or the specified function inside the library.
To use a backslash (\) character as a directory separator in the libraryPath parameter, you must enter a double backslash (\\). The single backslash is a reserved character.
Examples
