C External Function

Select the C External Function part to access a C function from the VisualAge environment. By connecting to the C External Function part, other parts can call the external function, pass parameters to the function, and retrieve the results from the function.

To use the C External Function part, you must have access to the header (.H) file defining the data types used by the external function. VisualAge can parse the C source code and header files to determine which parameters are passed. VisualAge objects can be used as parameters to C functions, and VisualAge handles any data type conversion necessary.
