.SH DESCRIPTION

.LP
The getdns_list type is used to manage heterogeneous indexed lists name/value pairs in which the data types of the values include
.RS 3
.br
getdns_bindata
.br
getdns_dict
.br
getdns_list
.br
uint32_t
.RE

.LP
The destroy function performs a "deep" destroy, freeing storage for all of the members
of the list before destroying the list.  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.
