nvpair Name-value pair to be processed. nelem Address to store the number of elements in value. val Address to store the value or the starting address of the array value. DESCRIPTION
These functions retrieve the value of nvpair. The data type of nvpair must match the interface 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(3NVPAIR). The value of an nvpair may not be retrieved after the nvpair has been removed from or replaced in an nvlist. Replacement can occur during pair additions to nvlists created with NV_UNIQUE_NAME_TYPE and NV_UNIQUE_NAME. See nvlist_alloc(3NVPAIR). RETURN VALUES
These functions return 0 on success and an error value on failure. ERRORS
These functions will fail if: EINVAL Either one of the arguments is NULL or the type of nvpair does not match the function name. ATTRIBUTES
