|

|
|
+ Macro ANSI C definition Traditional C definition
|
|

|
|
+ PTR `void *' `char *'
|
|
+ LONG_DOUBLE `long double' `double'
|
|
+ VOLATILE `volatile' `'
|
|
+ SIGNED `signed' `'
|
|
+ PTRCONST `void *const' `char *'
|
|
+ ANSI_PROTOTYPES 1 not defined
|
|
+
|
|
+ CONST is also defined, but is obsolete. Just use const.
|
|
+
|
|
+ obsolete -- DEFUN (name, arglist, args)
|
|
+
|
|
+ Defines function NAME.
|
|
+
|
|
+ ARGLIST lists the arguments, separated by commas and enclosed in
|
|
+ parentheses. ARGLIST becomes the argument list in traditional C.
|
|
+
|
|
+ ARGS list the arguments with their types. It becomes a prototype in
|
|
+ ANSI C, and the type declarations in traditional C. Arguments should
|
|
+ be separated with `AND'. For functions with a variable number of
|
|
+ arguments, the last thing listed should be `DOTS'.
|
|
+
|
|
+ obsolete -- DEFUN_VOID (name)
|
|
+
|
|
+ Defines a function NAME, which takes no arguments.
|
|
+
|
|
+ obsolete -- EXFUN (name, (prototype)) -- obsolete.
|
|
+
|
|
+ Replaced by PARAMS. Do not use; will disappear someday soon.
|
|
+ Was used in external function declarations.
|
|
+ In ANSI C it is `NAME PROTOTYPE' (so PROTOTYPE should be enclosed in
|
|
+ parentheses). In traditional C it is `NAME()'.
|
|
+ For a function that takes no arguments, PROTOTYPE should be `(void)'.
|
|
+
|
|
+ obsolete -- PROTO (type, name, (prototype) -- obsolete.
|
|
+
|
|
+ This one has also been replaced by PARAMS. Do not use.
|
|
+
|
|
+ PARAMS ((args))
|
|
+
|
|
+ We could use the EXFUN macro to handle prototype declarations, but
|
|
+ the name is misleading and the result is ugly. So we just define a
|
|
+ simple macro to handle the parameter lists, as in:
|
|
+
|
|
+ static int foo PARAMS ((int, char));
|
|
+
|
|
+ This produces: `static int foo();' or `static int foo (int, char);'
|
|
+
|
|
+ EXFUN would have done it like this:
|
|
+
|
|
+ static int EXFUN (foo, (int, char));
|
|
+
|
|
+ but the function is not external...and it's hard to visually parse
|
|
+ the function name out of the mess. EXFUN should be considered
|
|
+ obsolete; new code should be written to use PARAMS.
|
|
+
|
|
+ DOTS is also obsolete.
|
|
+
|
|
+ Examples:
|
|
+
|
|
+ extern int printf PARAMS ((const char *format, ...));
