@ -241,6 +241,23 @@ to implement it. Use something like
instead.
Don't use "variadic macros", such as
#define DBG(format, args...) fprintf(stderr, format, ## args)
as not all C compilers support them. Use macros that take a fixed
number of arguments, such as
#define DBG0(format) fprintf(stderr, format)
#define DBG1(format, arg1) fprintf(stderr, format, arg1)
#define DBG2(format, arg1, arg2) fprintf(stderr, format, arg1, arg2)
...
or something such as
#define DBG(args) printf args
snprintf() -> g_snprintf()
snprintf() is not available on all platforms, so it's a good idea to use the
g_snprintf() function declared by <glib.h> instead.
