Use#include <gjl.h>to get this prototype:void qvsum(fortran_quadruple_precision * x_, const fortran_integer * n_);
NB: The definition of C/C++ data types fortran_ xxx, and the mapping of Fortran external names to C/C++ external names, is handled by the C/C++ header file. That way, the same function or subroutine name can be used in C, C++, and Fortran code, independent of compiler conventions for mangling of external names in these programming languages.
