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.
