virtual ~WvFdStream()
Destroys the stream and invokes close().
virtual bool isok() const
return true if the stream is actually usable right now
virtual size_t uread(void *buf, size_t count)
unbuffered I/O functions; these ignore the buffer, which is handled by read().
virtual size_t uwrite(const void *buf, size_t count)
unbuffered I/O functions; these ignore the buffer, which is handled by write().
int getrfd() const
Returns the Unix file descriptor for reading from this stream.
virtual bool post_select(SelectInfo &si)
post_select() is called after ::select(), and returns true if this object is now ready.
void setfd(int fd)
Sets the file descriptor for both reading and writing.
WvFdStream(int rwfd=-1)
Creates a WvStream from an existing file descriptor.
virtual void maybe_autoclose()
Auto-close the stream if the time is right.
int getfd() const
Returns the Unix file descriptor for reading and writing.
void set_close_on_exec(bool close_on_exec)
Make the fds on this stream close-on-exec or not.
Unified support for streams, that is, sequences of bytes that may or may not be ready for read/write ...
virtual void close()
Closes the file descriptors.
int getwfd() const
Returns the Unix file descriptor for writing to this stream.
Base class for streams built on Unix file descriptors.
virtual void pre_select(SelectInfo &si)
pre_select() sets up for eventually calling ::select().
void set_nonblock(bool nonblock)
Make the fds on this stream blocking or non-blocking.
bool shutdown_read
Have we actually shut down the read/write sides?
int wfd
The file descriptor for writing.
int rfd
The file descriptor for reading.
