.SH DESCRIPTION

.LP
The getdns_dict type is used to manage name/value pairs in which the names are strings and the data types of the values are heterogeneous and include
.RS 3

.LP
The destroy function performs a "deep" destroy, freeing storage for all of the members
of the dictionary before destroying the dictionary.  There are a number of helper
functions that provide access to the dictionary 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_dict
the dictionary to destroy

.SH "RETURN VALUES"

Upon successful completion the getdns_dict_create function returns a valid
(empty) dictionary structure that should be freed via a call to
getdns_dict_destroy.  If a parameter in invalid or in the event of some error
getdns_dict_create returns NULL.
