There are _far_ more uses of __attribute__((format...) than __printf(...) I generally go with what's more commonly used, especially when it's 206 to 8, and 1 of the 8 is the #define itself. $ grep -rP --include=*.[ch] "__attribute__.*format" * | wc -l 206 $ grep -rP --include=*.[ch] -w "__printf" * | wc -l 8 -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
