A bit cleaner: #ifndef(MAX_IO_SIZE) # define MAX_IO_SIZE_DEFAULT (8*1024*1024) # if defined(SSIZE_MAX) && (SSIZE_MAX < MAX_IO_SIZE_DEFAULT) # define MAX_IO_SIZE SSIZE_MAX # else # define MAX_IO_SIZE MAX_IO_SIZE_DEFAULT # endif #endif -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
