.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.
