Constants
Functions
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, 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)
pipe2(flags)—Creates a pipe, with flags.
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.
preadv2(fd, bufs, offset, flags)—Reads data, with several options.
Returns a handle to Linux’s /proc directory.
Returns a handle to Linux’s /proc/self directory.
Returns a handle to Linux’s /proc/self/fd directory.
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.
pwritev2(fd, bufs, offset, flags)—Writes data, with several options.
read(fd, buf)—Reads from a stream.
readv(fd, bufs)—Reads from a stream into multiple buffers.
STDERR_FILENO—Standard error.
STDIN_FILENO—Standard input.
STDOUT_FILENO—Standard output.
userfaultfd(flags)
write(fd, buf)—Writes to a stream.
writev(fd, bufs)—Writes to a stream from multiple buffers.
