Replace FWRITE with a function
In a few places we use the FWRITE() macro to open a file, replace it's contents with a given string and close it again. There's no real reason this needs to be a macro rather than just a function though. Turn it into a function 'write_file()' and make some ancillary cleanups while we're there: - Add a return code so the caller can handle giving a useful error message - Handle the case of short write()s (unlikely, but possible) - Add O_TRUNC, to make sure we replace the existing contents entirely Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Stefano Brivio <sbrivio@redhat.com>
