Hi there,

in order to support both C and C++ compilers, it would be nice to add a conditional `extern "C"' wrapper to c_interface.h. While we are at it, we should probably also add the usual guard against multiple inclusion. The standard way to do that is as follows:

#ifndef _Yap_c_interface_h #define _Yap_c_interface_h 1 /* __BEGIN_DECLS should be used at the beginning of the C declarations, so that C++ compilers don't mangle their names. __END_DECLS is used at the end of C declarations. */ #undef __BEGIN_DECLS #undef __END_DECLS #ifdef __cplusplus # define __BEGIN_DECLS extern "C" { # define __END_DECLS } #else # define __BEGIN_DECLS /* empty */ # define __END_DECLS /* empty */ #endif

__BEGIN_DECLS

put current contents of c_interface.h here

__END_DECLS

#endif

All the best
