There are a number of helper functions that provide access to the list object, see their respective man pages. .LP .I userarg pass this argument to the user specified memory management functions for operations on lists created using extended memory functions .LP .I this_list the list to destroy .SH "RETURN VALUES" Upon successful completion the getdns_list_create function returns a valid (empty) list structure that should be freed via a call to getdns_list_destroy. If a parameter in invalid or in the event of some error getdns_list_create returns NULL. .SH EXAMPLES TBD .SH SEE ALSO .BR libgetdns (3), .BR getdns_dict (3), .BR getdns_list_get (3), .BR getdns_list_set (3)
