The following text assumes that you are writing in Silverfrost C/C++ and are calling
an FTN95 relocatable binary library (RLB) or dynamic link library (DLL).
When calling FTN95 routines from C/C++, the following major points should be
� Fortran arguments are passed by
reference rather than value.
� All Fortran external names are upper
case (regardless of the case of the original source text).
� Fortran character variables have no
simple analogue in C/C++.
If you have a C/C++ main program calling a Fortran RLB, then the main program
should call the library initialisation routine if there is one. Failure to do
so will result in unpredictable behaviour. If you are calling a DLL then the
initialisation will probably take place automatically when the DLL is loaded.
For a practical example of how to call an FTN95 DLL from a Visual C++ program
see the following topic, which includes example source code.
