NVLIST_REMOVE(9F) Kernel Functions for Drivers NVLIST_REMOVE(9F)

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.
