filter_ignore_parameter_values

Install a UhmServer:compare-messagess filter function which will override the default comparison function to one which ignores differences in the values of the given query parameter_names.

The named parameters must still be present in the query, however.

The filter will remain in place for the lifetime of the Server, until uhm_server_compare_messages_remove_filter() is called with the returned filter ID.

Note that currently only one of the installed comparison functions will be used. This may change in future.

Parameters:

this	a Server
parameter_names	null-terminated array of parameter names to ignore

Returns:

opaque filter ID used with compare_messages_remove_filter to remove the filter later
