Interface Level

Solaris DDI specific (Solaris DDI)

Parameters

nvl

The nvlist_t to be processed.

nvp

The nvpair_t (name-value pair) to be processed.

name

Name of the name-value pair (nvpair).

nelem

Number of elements in value (that is, array size).

val

Value or starting address of the array value.

Description

These functions add a new name-value pair to an nvlist_t. The memory allocation policy follows that specified in nvlist_alloc(), nvlist_unpack(), or nvlist_dup(). See nvlist_alloc(9F). The uniqueness of nvpair name and data types follows the nvflag argument specified in nvlist_alloc().

If NV_UNIQUE_NAME was specified for nvflag, existing nvpairs with matching names are removed before the new nvpair is added.

If NV_UNIQUE_NAME_TYPE was specified for nvflag, existing nvpairs with matching names and data types are removed before the new nvpair is added.

If neither was specified for nvflag, the new nvpair is unconditionally added at the end of the list. The library preserves the order of the name-value pairs across packing, unpacking, and duplication.

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.

The nvlist_add_boolean() function is deprecated. Instead, use the nvlist_add_boolean_value() function.

Return Values

0

success

EINVAL

invalid argument

ENOMEM

insufficient memory

Context

These functions can be called from interrupt context only if (1) the default allocator is used and the KM_NOSLEEP flag is set, or (2) the specified allocator did not sleep for free memory (for example, if it uses a pre-allocated buffer for memory allocations).

See nvlist_alloc(9F) for a description of pluggable allocators and KM_NOSLEEP. These functions can be called from user or kernel context in all cases.
