|
||||
|
||||
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.
|
||||
|
||||

||||
