IsFunction()

Syntax

Result.l = IsFunction(#Library, FunctionName$)

Checks if the library, previously opened using the OpenLibrary() command, contains the given function. Note that the function name is always case sensitive.

Parameters

#Library - The numeric identifier of the library you want to find a function in. This must be the same number that you use when you called OpenLibrary().

FunctionName$ - A string containing the name of the function you want to find.

Return value

Result - The address in memory of the function from the library, which is useful for using with the CallFunctionFast() or CallCFunctionFast() commands. If the address is zero then the function cannot be found and you should not try to call it.
