va_arg
Returns the current argument from a variable argument list.
The va_arg macro allows the use of a variable number of arguments within a function. va_arg returns the current argument in the list, argument_list, with an expected data type of datatype. Before va_arg can be used, it must be Initialized with the command va_first. Unlike the C macro with the same name, va_arg does not automatically increment argument_list to the next argument within the list. Instead va_next must be used to find the next argument.
