You can use the following fragment:

static int foobar(void *info, char *buf) { return 1; }

...

      /* disable output from glpk api routines */
      _glp_lib_print_hook(foobar, NULL);
...

      /* enable output from glpk api routines */
      _glp_lib_print_hook(NULL, NULL);

(Please note that _glp_lib_print_hook is not prototyped in 4.14.)
