Name

libnvpair– name-value pair library

Synopsis

cc [ flag... ] file... -lnvpair [ library... ]
#include <libnvpair.h>

Description

The libnvpair library exports a set of functions for managing name-value pairs.

The library defines four opaque handles:

nvpair_t: handle to a name-value pair
nvlist_t: handle to a list of name-value pairs
nv_alloc_t: handle to a pluggable allocator
nv_alloc_ops_t: handle to pluggable allocator operations

The library supports the following operations:

Allocate and free an nvlist_t.
Specify the allocater to be used when manipulating an nvlist_t.
Add and remove an nvpair_t from a list.
Search nvlist_t for a specified name pair.
Pack an nvlist_t into a contiguous buffer.
Expand a packed nvlist into a searchable nvlist_t.
