abcdefghijklmnopqr stuvwxyz This header defines macros to access the individual arguments of a list of unnamed arguments whose number and types are not known to the called function. A function may accept a varying number of additional arguments without corresponding parameter declarations by including a comma and three dots (,...) after its regular named parameters: return_type function_name ( parameter_declarations , ... );  To access these additional arguments the macros va_start, va_arg and va_end, declared in this header, can be used: First, va_start initializes the list of variable arguments as a va_list. Subsequent executions of va_arg yield the values of the additional arguments in the same order as passed to the function. Finally, va_end shall be executed before the function returns.
