va_arg
Returns the current argument from a variable argument list.
Syntax
`
variable = va_arg ( argument_list, datatype )
`
Description
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.
Example
See the `Va_First()` examples.
