int snmp_set_var_typed_value	(	netsnmp_variable_list *	newvar,
		u_char	type,
		const u_char *	val_str,
		size_t	val_len
	)

snmp_set_var_typed_value is used to set data into the netsnmp_variable_list structure.

Used to return data to the snmp request via the netsnmp_request_info structure's requestvb pointer.

Parameters:

	newvar	the structure gets populated with the given data, type, val_str, and val_len.
	type	is the asn data type to be copied
	val_str	is a buffer containing the value to be copied into the newvar structure.
	val_len	the length of val_str

Returns:: returns 0 on success and 1 on a malloc error

Examples:: delayed_instance.c.
