[Help-glpk] How to disable messages of lpx_simplex?

[Regis Behmo]

I got the same problem as http://www.mail-archive.com/address@hidden/msg00473.html

I want to disable the run-time reporting of the standard output and I find the answer given in the above mentioned thread not very explicit. I tried to do 

lib_set_fault_hook(NULL, NULL);
lib_set_print_hook(NULL, NULL);

before executing lpx_simplex, but it doesn't solve anything.

Thanks for your help
