NVLIST_REMOVE 3NVPAIR "Feb 2, 2004"
NAME
nvlist_remove, nvlist_remove_all - remove name-value pairs
SYNOPSIS

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

int nvlist_remove(nvlist_t *nvl, const char *name,
 data_type_t type);

int nvlist_remove_all(nvlist_t *nvl, const char *name);
PARAMETERS
nvl

The nvlist_t to be processed.

name

Name of the name-value pair to be removed.

type

Data type of the nvpair to be removed.

DESCRIPTION

The nvlist_remove() function removes the first occurrence of nvpair that matches the name and the type.

The nvlist_remove_all() function removes all occurrences of nvpair that match the name, regardless of type.

Multiple threads can simultaneously read the same nvlist_t but only one thread can actively change a given nvlist_t at a time. The caller is responsible for the synchronization.

RETURN VALUES

These functions return 0 on success and an error value on failure.

ERRORS

These functions will fail if: EINVAL

There is an invalid argument.

ENOENT

No name-value pairs were found to match the criteria specified by name and type.
