Notes
A FunctionNotFoundException is raised when a Soft Declare statement such as this:
fails to find the specified function or library and it cannot be loaded. If a “hard” Declare fails to load the function, the application will not run at all.
To determine whether the function can be loaded without actually using the Soft Declare, use the System module’s IsFunctionAvailable method. It returns a Boolean indicating whether the function can be loaded on the user’s machine.
Sample Code
The following example adds a RuntimeException handler to the above example.
Soft Declare Function getpid Lib "libc" () As Integer
Exception err As FunctionNotFoundException
MsgBox(err.Message + " Error No.: " + Str(err.ErrorNumber))
Exception err As FunctionNotFoundException
MsgBox(err.Message + " Error No.: " + Str(err.ErrorNumber))
