int ham_verbose( const char *nodename,
                 int op,
                 int value);

Arguments:

nodename

The name of the node on which to make the change, or NULL if you want to change the verbosity on the current node.

op

• VERBOSE_SET_INCR — increment the verbosity.
• VERBOSE_SET_DECR — decrement the verbosity.
• VERBOSE_SET — set the verbosity to a specific value.
• VERBOSE_GET — get the verbosity.

value

The increment, decrement, or specific value for the verbosity, depending on the value of op. The value must be a non-negative integer. If value is zero, the function uses 1 for the increment or decrement.
