Module posish::io

I/O operations.

Structs

Error	The error type for posish APIs.
PipeFlags	O_* constants for use with pipe2.
PollFd	pollfd
PollFdVec	A Vec of pollfd.
PollFlags	POLL*
UserFaultFdFlags	The O_* flags accepted by userfaultfd.

Constants

ICANON	Re-export ICANON.
PIPE_BUF	Re-export PIPE_BUF.

Functions

dup	dup(fd)
ioctl_fionread	ioctl(fd, FIONREAD).
ioctl_tcgets	ioctl(fd, TCGETS)
ioctl_tiocgwinsz	ioctl(fd, TIOCGWINSZ).
is_read_write	Returns a pair of booleans indicating whether the file descriptor is readable and/or writeable, respectively. Unlike is_file_read_write, this correctly detects whether sockets have been shutdown, partially or completely.
isatty	isatty(fd)
pipe2	pipe2(flags)
pread	pread(fd, buf.as_ptr(), bufs.len(), offset)
preadv	preadv(fd, bufs.as_ptr(), bufs.len(), offset)
preadv2	preadv2(fd, bufs.as_ptr(), bufs.len(), offset, flags)
pwrite	pwrite(fd, bufs.as_ptr(), bufs.len())
pwritev	pwritev(fd, bufs.as_ptr(), bufs.len(), offset)
pwritev2	pwritev2(fd, bufs.as_ptr(), bufs.len(), offset, flags)
read	read(fd, buf.as_ptr(), buf.len())
readv	readv(fd, bufs.as_ptr(), bufs.len())
ttyname	ttyname_r(fd)
userfaultfd⚠	userfaultfd(flags)
write	write(fd, buf.ptr(), buf.len())
writev	writev(fd, bufs.as_ptr(), bufs.len())

Type Definitions

Result	A specialized Result type for posish APIs.
Termios	Re-export termios.
Winsize	Re-export winsize.
