- This header, <stdarg.h>, declares type va_list and defines macros: va_start, va_arg, va_end;
- for advancing through a list of arguments whose number and types are not known to the
- called function when it is translated.
-
- A function may be called with a variable number of arguments of varying types.
- The rightmost argument plays a special role in the access mechanism, and will
- be designated paramN in this and subsequent descriptions.
-
- The type va_list is a type suitable for holding information needed by the
- macros va_start, va_arg, and va_end. If access to the varying arguments
- is desired, the called function shall declare an object (referred to as ap
- in these descriptions) having type va_list. The object ap may be passed as
- an argument to another function; if the receiving function invokes the va_arg macro
- with parameter ap, the value of ap in the calling function becomes indeterminate
- and must be passed to the va_end macro prior to any further reference to ap.
-
- The va_start and va_arg macros must be implemented as macros, not as actual
- functions. The va_start and va_end macros must be invoked in the
- function accepting a varying number of arguments, if access to the varying
- arguments is desired.

-/** @{
- The va_arg macro expands to an expression that has the type and value of
- the next argument in the call. The parameter ap shall be the same as the
- va_list ap initialized by va_start. Each invocation of va_arg modifies ap
- so that the values of successive arguments are returned in turn. The
- parameter type is a type name specified such that the type of a pointer to
- an object that has the specified type can be obtained simply by postfixing
- a * to type. If there is no actual next argument, or if type is not
- compatible with the type of the actual next argument (as promoted
- according to the default argument promotions), the behavior is undefined.
-
- Synopsys: type va_arg(va_list ap, type);
-
- @param ap An object of type va_list that was initialized by a prior
- invocation of va_start.
-
- @param type A type name specifying the type of the parameter to be retrieved.
-
- @return The first invocation of the va_arg macro after that of the
- va_start macro returns the value of the argument after that
- specified by paramN. Successive invocations return the values
- of the remaining arguments in succession.
