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);

nvl

name

Name of the name-value pair (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
