Module posish::io [−][src]
Expand description
I/O operations.
Structs
O_*
constants for use with dup2
.
The error type for posish APIs.
MAP_*
flags for use with mmap
.
A wrapper around io_lifetimes::OwnedFd
which closes the file descriptor
using posish’s own close
rather than libc’s close
.
struct pollfd
A Vec
of pollfd
.
POLL*
PROT_*
flags for use with mmap
.
Constants
Functions
close(raw_fd)
—Closes a RawFd
directly.
dup(fd)
—Creates a new OwnedFd
instance that shares the same
underlying file description as fd
.
dup2(fd, new)
—Creates a new OwnedFd
instance that shares the
same underlying file description as the existing OwnedFd
instance,
closing new
and reusing its file descriptor.
dup3(fd, new, flags)
—Creates a new OwnedFd
instance that shares the
same underlying file description as the existing OwnedFd
instance,
closing new
and reusing its file descriptor, with flags.
ioctl(fd, FIOCLEX)
ioctl(fd, FIONBIO, &value)
—Enables or disables non-blocking mode.
ioctl(fd, FIONREAD)
—Returns the number of bytes ready to be read.
ioctl(fd, TCGETS)
ioctl(fd, TIOCGWINSZ)
Returns a pair of booleans indicating whether the file descriptor is readable and/or writeable, respectively.
isatty(fd)
—Tests whether a file descriptor refers to a terminal.
mmap(fd, len, prot, flags, fd, offset)
munmap(ptr, len)
pipe()
—Creates a pipe.
pread(fd, buf, offset)
—Reads from a file at a given position.
preadv(fd, bufs, offset)
—Reads from a file at a given position into
multiple buffers.
pwrite(fd, bufs)
—Writes to a file at a given position.
pwritev(fd, bufs, offset)
—Writes to a file at a given position from
multiple buffers.
read(fd, buf)
—Reads from a stream.
readv(fd, bufs)
—Reads from a stream into multiple buffers.
STDERR_FILENO
—Standard error, borrowed.
STDIN_FILENO
—Standard input, borrowed.
STDOUT_FILENO
—Standard output, borrowed.
STDERR_FILENO
—Standard error, owned.
STDIN_FILENO
—Standard input, owned.
STDOUT_FILENO
—Standard output, owned.
ttyname_r(fd)
write(fd, buf)
—Writes to a stream.
writev(fd, bufs)
—Writes to a stream from multiple buffers.
