nvlist_remove 9F "16 Jan 2006" "SunOS 5.11" "Kernel Functions for Drivers"
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

Solaris DDI specific (Solaris 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.
