The function can take variable parameters. The user can use stdarg
library to create functions that take variable parameters.
Function dependent.
The stdarg library allows the user to create functions that supports
variable arguments.
The function that will accept a variable number of arguments must have
at least one actual, known parameters, and it may have more. The
number of arguments is often passed to the function in one of its actual
parameters. If the variable-length argument list can involve more that
one type, the type information is generally passed as well. Before
processing can begin, the function creates a special argument pointer of
type va_list.
