Is it just a GCC warning or rather a combination of GCC and some misguided glibc decorator to force check the return of read/write? Naming the compiler versions and the warning flag which enables this would be useful. We don't see it building with normal warning level today. > Fix the warnings by casting the return values to void to indicate that > ignoring them is intentional. > ret = read(fd, &byte, sizeof(byte)); > (void)ret; Can you not cast the read() to void directly? -- pw-bot: cr
