Colin Patrick McCabe	4de7fd4931	common: safe_io: allow C files to include safe_io ... Don't use extern C unless we're compiling with C++. This allows C files to include safe_io.h Signed-off-by: Colin McCabe <colin.mccabe@dreamhost.com>	2011-02-10 05:47:42 -08:00
Colin Patrick McCabe	a743e314b9	common:safe_io: create exact and non-exact variant ... Create safe_read_exact, which fails with -EDOM unless it reads exactly the requested number of bytes. More often, what we want is the semantics of safe_read, which returns the number of bytes it read, or negative on error. Likewise for pread. Write doesn't need variants because failing to write all the bytes is always an error. Signed-off-by: Colin McCabe <colin.mccabe@dreamhost.com>	2011-02-10 04:58:47 -08:00
