NAME

       nvlist_next_nvpair, nvpair_name, nvpair_type - return data regarding name-value pairs

SYNOPSIS

       #include <sys/nvpair.h>

       nvpair_t *nvlist_next_nvpair(nvlist_t *nvl, nvpair_t *nvpair);

       char *nvpair_name(nvpair_t *nvpair);

       data_type_t nvpair_type(nvpair_t *nvpair);

INTERFACE LEVEL

       Solaris DDI specific (Solaris DDI)

PARAMETERS

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

       nvpair	Handle to a name-value pair.

DESCRIPTION

       The  nvlist_next_nvpair()  function  returns a handle to the next name-value pair (nvpair) in the list following nvpair. If nvpair is NULL,
       the first pair is returned. If nvpair is the last pair in the nvlist_t, NULL is returned.

       The nvpair_name() function returns a string containing the name of nvpair.

       The nvpair_type() function retrieves the value of the nvpair in the form of enumerated type data_type_t. This  is  used	to  determine  the
       appropriate nvpair_*() function to call for retrieving the value.

RETURN VALUES

       For nvpair_name(): a string containing the name.

       For nvpair_type(): an enumerated data type data_type_t. Possible values for data_type_t are:

       DATA_TYPE_BOOLEAN
       DATA_TYPE_BOOLEAN_VALUE
       DATA_TYPE_BYTE
       DATA_TYPE_INT8
       DATA_TYPE_UINT8
       DATA_TYPE_INT16
       DATA_TYPE_UINT16
       DATA_TYPE_INT32
       DATA_TYPE_UINT32
       DATA_TYPE_INT64
       DATA_TYPE_UINT64
       DATA_TYPE_STRING
       DATA_TYPE_NVLIST
       DATA_TYPE_BOOLEAN_ARRAY
       DATA_TYPE_BYTE_ARRAY
       DATA_TYPE_INT8_ARRAY
       DATA_TYPE_UINT8_ARRAY
       DATA_TYPE_INT16_ARRAY
       DATA_TYPE_UINT16_ARRAY
       DATA_TYPE_INT32_ARRAY
       DATA_TYPE_UINT32_ARRAY
       DATA_TYPE_INT64_ARRAY
       DATA_TYPE_UINT64_ARRAY
       DATA_TYPE_STRING_ARRAY
       DATA_TYPE_NVLIST_ARRAY

       After  nvpairs  is  removed  from or replaced in an nvlist, it cannot be manipulated. This includes nvlist_next_nvpair(), nvpair_name() and
       nvpair_type(). Replacement can  happen  during  pair  addition  on  nvlists  created  with  NV_UNIQUE_NAME_TYPE	and  NV_UNIQUE_NAME.   See
       nvlist_alloc(9F) for more details.

CONTEXT

       These functions can be called from user or interrupt context.
