set_native_filter

Syntax

native set_native_filter(const handler[]);

Description

Sets a native filter. This must be first set in plugin_natives(), but future calls will
simply set a new filter.
This filter will allow your plugin to load even if its modules aren't loaded. For example,
if Fun isn't loaded and you use set_user_frags, your plugin will still load. However, if you
attempt to call this native, your filter will intercept it with these parameters:

public function native_filter(const name[], index)
native - name of native
index - index of native
trap - 0 if native couldn't be found, 1 if native use was attempted

If you return PLUGIN_HANDLED, no error is thrown. If you return PLUGIN_CONTINUE,
your plugin will have a run-time-error. To print your own error, or change the default,
you can return PLUGIN_HANDLED or return PLUGIN_CONTINUE and use set_error_filter.
If you return PLUGIN_CONTINUE when trap is 0, the plugin will ABORT AND FAIL TO LOAD!
When trap is 0, it is unsafe to use natives that modify the server or use other plugins.
