NVLIST_REMOVE 9F "Jan 16, 2006"
NAME
nvlist_remove, nvlist_remove_all - remove name-value pairs
SYNOPSIS
#include <sys/nvpair.h>

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

int nvlist_remove_all(nvlist_t *nvl, const char *name);
INTERFACE LEVEL
illumos DDI specific (illumos DDI)
PARAMETERS
nvl

The list of name-value pairs (nvlist_t) to be processed.

name

Name of the name-value pair (nvpair) 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 may 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.
CONTEXT
The nvlist_remove() and nvlist_remove_all() functions can be called from user, interrupt, or kernel context.
ERRORS
EINVAL

There is an invalid argument.

ENOENT

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