va_arg

Returns the current argument from a variable argument list.

Syntax
	variable = va_arg ( argument_list, DataType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 first va_arg use, argument_list must be initialized with 
		  the command KeyPgVaFirst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 KeyPgVaNextva_next must be used to find the next argument in 
		  adjusting argument_list.

	Not supported when using CompilerOptgen-gen gcc.  Use KeyPgCvaListCva_List variadic argument list 
	type for cross platform compatibility.

Example
	See the KeyPgVaFirstVa_First() examples.

Dialect Differences
	* Not available in the CompilerOptlang-lang qb dialect unless referenced with the 
	  alias __va_arg.

Differences from QB
