Function posish::fs::is_file_read_write [−][src]
pub fn is_file_read_write<'f, Fd: AsFd<'f>>(fd: Fd) -> Result<(bool, bool)>
Expand description
fcntl(fd, F_GETFL) & O_ACCMODE
. Returns a pair of booleans indicating
whether the file descriptor is readable and/or writeable, respectively.
This is only reliable on files; for example, it doesn’t reflect whether
sockets have been shut down; for general I/O handle support, use
io::is_read_write
.
