Macros
|
||
|
|
PTR - Generic pointer type
|
||
|
|
LONG_DOUBLE - `long double' type
|
||
|
|
CONST - `const' keyword
|
||
|
|
VOLATILE - `volatile' keyword
|
||
|
|
SIGNED - `signed' keyword
|
||
|
|
PTRCONST - Generic const pointer (void *const)
|
||
|
|
|
||
|
|
EXFUN(name, prototype) - declare external function NAME
|
||
|
|
with prototype PROTOTYPE
|
||
|
|
DEFUN(name, arglist, args) - define function NAME with
|
||
|
|
args ARGLIST of types in ARGS
|
||
|
|
DEFUN_VOID(name) - define function NAME with no args
|
||
|
|
AND - argument separator for ARGS
|
||
|
|
NOARGS - null arglist
|
||
|
|
DOTS - `...' in args
|
||
|
|
|
||
|
|
For example:
|
||
|
|
extern int EXFUN(printf, (CONST char *format DOTS));
|
||
|
|
int DEFUN(fprintf, (stream, format),
|
||
|
|
FILE *stream AND CONST char *format DOTS) { ... }
|
||
|
|
void DEFUN_VOID(abort) { ... }
