SYNOPSIS

 
#include <sys/nvpair.h> 
int nvpair_value_byte(nvpair_t *nvpair, uchar_t *val);
 int nvpair_value_int16(nvpair_t *nvpair, int16_t *val);
 int nvpair_value_uint16(nvpair_t *nvpair, uint16_t *val);
 int nvpair_value_int32(nvpair_t *nvpair, int32_t *val);
 int nvpair_value_uint32(nvpair_t *nvpair, uint32_t *val);
 int nvpair_value_int64(nvpair_t *nvpair, int64_t *val);
 int nvpair_value_uint64(nvpair_t *nvpair, uint64_t *val);
 int nvpair_value_string(nvpair_t *nvpair, char **val);
 int nvpair_value_byte_array(nvpair_t *nvpair, uchar_t **val, uint_t *nelem);
 int nvpair_value_int16_array(nvpair_t *nvpair, int16_t **val, uint_t *nelem);
 int nvpair_value_uint16_array(nvpair_t *nvpair, uint16_t **val, uint_t *nelem);
 int nvpair_value_int32_array(nvpair_t *nvpair, int32_t **val, uint_t *nelem);
 int nvpair_value_uint32_array(nvpair_t *nvpair, uint32_t **val, uint_t *nelem);
 int nvpair_value_int64_array(nvpair_t *nvpair, int64_t **val, uint_t *nelem);
 int nvpair_value_uint64_array(nvpair_t *nvpair, uint64_t **val, uint_t *nelem);
 int nvpair_value_string_array(nvpair_t *nvpair, char ***val, uint_t *nelem);

INTERFACE LEVEL

 

Solaris DDI specific (Solaris DDI)

PARAMETERS

 
nvpair
Name-value pair (nvpair) to be processed.
nelem
Address to store the number of elements in value.
val
Address to store the value or starting address of array value.

DESCRIPTION

 

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)

RETURN VALUES

 
0
Success
EINVAL
Either one of the arguments is NULL or type of nvpair does not match the interface name.

CONTEXT

 

These functions can be called from user or interrupt context.
