       Solaris DDI specific (Solaris DDI)

		 Name-value pair (nvpair) to be processed.

		 Address to store the number of elements in value.

		 Address to store the  value  or  starting  address  of	 array

       These  functions	 retrieve the value of nvpair. The data type of nvpair
       must match the function name for the call to be successful.

       There is no nvpair_value_boolean(); the existence of the	 name  implies
       the value is true.

       For  array data types, including string, the memory containing the data
       is managed by the library and references to  the	 value	remains	 valid
       until  nvlist_free()  is	 called	 on  the nvlist_t from which nvpair is
       obtained. See nvlist_free(9F)

       The value of an nvpair may not be retrieved  after  the	nvpair	having
       been removed from or replaced in an nvlist. Replacement can happen dur‐
       ing pair addition  on  nvlists  created	with  NV_UNIQUE_NAME_TYPE  and
       NV_UNIQUE_NAME. See nvlist_alloc(9F) for more details.


		 Either	 one  of  the arguments is NULL or type of nvpair does
		 not match the interface name.

       These functions can be called from user, interrupt, or kernel context.
