ln_input number := nvl('&1',0);
nvl provides a "default" value for missing i.e. NULL variables, so if &1has not been assigned to, number will become 0.

PARAMETERS

       nvl	The nvlist_t (name-value pair list) to be processed.

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

       name	Name of the nvpair (name-value pair).

       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 uniqueness of nvpair name and data types follows the nvflag argument speci-
       fied for nvlist_alloc(). See nvlist_alloc(3NVPAIR).

       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 can actively change a given nvlist_t at a time. The  caller
       is responsible for the synchronization.

       The nvlist_add_boolean() function is deprecated. The nvlist_add_boolean_value() function should be used instead.

RETURN VALUES

       These functions return 0 on success and an error value on failure.

ERRORS

       These functions will fail if:

       EINVAL	       There is an invalid argument.

       ENOMEM	       There is insufficient memory.
