Note that it is safe to write "void foo();" indicating a function
with no return value, in all K+R compilers we have been able to test.
For declaring functions with prototypes, we also provide these:
PARAMS ((prototype))
-- for functions which take a fixed number of arguments. Use this
when declaring the function. When defining the function, write a
K+R style argument list. For example:
char *strcpy PARAMS ((char *dest, char *source));
...
char *
strcpy (dest, source)
char *dest;
char *source;
{ ... }
VPARAMS ((prototype, ...))
-- for functions which take a variable number of arguments. Use
PARAMS to declare the function, VPARAMS to define it. For example:
int printf PARAMS ((const char *format, ...));
...
int
printf VPARAMS ((const char *format, ...))
{
...
}
For writing functions which take variable numbers of arguments, we
also provide the VA_OPEN, VA_CLOSE, and VA_FIXEDARG macros. These
hide the differences between K+R <varargs.h> and C89 <stdarg.h> more
thoroughly than the simple VA_START() macro mentioned above.
VA_OPEN and VA_CLOSE are used *instead of* va_start and va_end.
Immediately after VA_OPEN, put a sequence of VA_FIXEDARG calls
corresponding to the list of fixed arguments. Then use va_arg
normally to get the variable arguments, or pass your va_list object
around. You do not declare the va_list yourself; VA_OPEN does it
for you.
Here is a complete example:
int
printf VPARAMS ((const char *format, ...))
{
int result;
VA_OPEN (ap, format);
VA_FIXEDARG (ap, const char *, format);
result = vfprintf (stdout, format, ap);
VA_CLOSE (ap);
return result;
}
You can declare variables either before or after the VA_OPEN,
VA_FIXEDARG sequence. Also, VA_OPEN and VA_CLOSE are the beginning
and end of a block. They must appear at the same nesting level,
and any variables declared after VA_OPEN go out of scope at
VA_CLOSE. Unfortunately, with a K+R compiler, that includes the
argument list. You can have multiple instances of VA_OPEN/VA_CLOSE
pairs in a single function in case you need to traverse the
argument list more than once.
For ease of writing code which uses GCC extensions but needs to be
portable to other compilers, we provide the GCC_VERSION macro that
simplifies testing __GNUC__ and __GNUC_MINOR__ together, and various
wrappers around __attribute__. Also, __extension__ will be #defined
to nothing if it doesn't work. See below.
This header also defines a lot of obsolete macros:
CONST, VOLATILE, SIGNED, PROTO, EXFUN, DEFUN, DEFUN_VOID,
AND, DOTS, NOARGS. Don't use them. */
