NAME

getdns_list, getdns_list_create, getdns_list_create_with_extended_memory_functions, getdns_list_create_with_memory_functions, getdns_list_destroy -- getdns list create and destroy routines

LIBRARY

DNS Resolver library (libgetdns, -lgetdns)

SYNOPSIS

#include <getdns.h>

getdns_list *
getdns_list_create ()

getdns_list *
getdns_list_create_with_extended_memory_functions

(void *userarg,
void *(*malloc)(void *userarg, size_t sz),
void *(*realloc)(void *userarg, void *buf, size_t sz),
void (*free)(void *userarg, void *buf)

getdns_list *
getdns_list_create_with_memory_functions

(void *userarg,
void *(*malloc)(size_t sz),
void *(*realloc)(void *buf, size_t sz),
void (*free)(void *buf)

void
getdns_list_destroy (getdns_list *this_dict)

DESCRIPTION

The getdns_list type is used to manage heterogeneous indexed lists name/value pairs in which the data types of the values include

getdns_bindata
getdns_dict
getdns_list
uint32_t

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.

userarg pass this argument to the user specified memory management functions for operations on lists created using extended memory functions

this_list the list to destroy

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.
