OpenMM_CWrapper.cpp

// -----------------------------------------------------------------------------
//       OpenMM(tm) PROTOTPYE C and Fortran wrapper functions (June 2009)
// -----------------------------------------------------------------------------
// This is the C++ implementation of the C wrappers for the OpenMM workshop.
// The functions here convert between C types and OpenMM's C++ objects
// and then call the appropriate OpenMM methods.
//
// Each C function comes in several forms -- one is intended to be called from C
// main programs, and the others from Fortran main programs. The Fortran ones
// typically just translates Fortran naming and argument conventions into C 
// and then calls the C function. In particular, gcc's gfortran compiler
// translates names into all-lowercase and appends an underscore, while
// Intel's ifort compiler tranlates names into all-uppercase and does not
// append an underscore.
//
// A C main program can use this just by including the OpenMM_CWrapper.h 
// header file that is included here as well. A Fortran 95 program can use
// the "use OpenMM" module which defines an interface to the Fortran-callable
// functions defined here. Fortran 77 programs have to call these directly;
// you can use an integer*8 to hold the pointers on any platform.
