Hello Andrew,
in glpk-java I use the glp_error_hook. I set it before calling
a function and use setjmp.
This is what my error handler looks like:
void glp_java_error_hook(void *in) {
/* free GLPK memory */
glp_free_env();
/* safely return */
longjmp(*((jmp_buf*)in), 1);
When in a callback a glp_functions fails this results
in the wrong long jump being executed because the glpk-java
wrapper library is not aware of the callback.
Is there a way to determine if the error hook function is
already set or not?
I am missing functions to retrieve the error hook function and
the info which could be used to build a chain of error
handlers.
Best regards
Xypron
