It might be cleaner/easier to do:

config = get_server_config_struct();
PINT_cached_config_get_server(fsid, config->host_id, server_type,  
&extent_array);

If you don't care about the server type, you can pass in:

  PINT_SERVER_TYPE_META|PINT_SERVER_TYPE_IO

Then with the returned extent_array, you can do:

is_my_handle = PINT_handle_in_extent_array(&extent_array, your_handle);

That function is defined in src/common/misc/extent-utils.h
