Other Type Keywords
The void data type is neither a scalar nor an aggregate. Use void as the
return type of a function, to indicate that the function does not return a
value. Use
void * as a pointer to an unspecified data type.
The
const and volatile type qualifiers do not define data types. Rather,
they associate attributes with other types. Use
const to specify that an
object is a constant and is not to be changed. Use
volatile to specify
that an object may change in ways unknown to the compiler.
Optimization is inhibited on
volatile objects. Inhibition of optimization
is necessary for objects such as memory mapped I/O registers or data
accessed by interrupt functions.
Calling Conventions
This section describes the standard i960 processor function calling
convention and describes how the compiler generates code to conform to
this calling convention.
