Re: [Help-glpk] C++ throw instead of C exit

Currently in case of fatal error all glpk routines call the routine
xerror (_glp_lib_xerror), which prints an error message and then
calls the standard function abort. It is assumed that the application
program can catch SIGABRT signal, if necessary.

To make the error handling more convenient I will add the following
api routine:

   void glp_error_hook(void (*func)(void *info), void *info);

The parameter func is a user-defined routine, which is installed to
be called from xerror; if it returns, xerror calls abort. The parameter
info is a transit pointer (magic cookie) passed to func.
