typedef struct ExtFct* ExtFctStructPtr;
If the external function is to be developed independently of the platform (Windows, Linux), then
it is not permissible to use the keyword __declspec(dllexport). This keyword is only required
under Windows. For instance, the following macro can be used under Qt:
#ifdef Q_WS_WIN
#else
#endif
The function is declared as follows:
If the screens, configured with "Run MyScreens", are used on the NCU and PCU/PC, then the
extension of the binary file must be omitted:
When the absolute path information is omitted, "Run MyScreens" first searches for the binary
file in the configured directory.
