Constructor & Destructor Documentation

unix_buffer::unix_buffer

(

void

)

[inline]

create an unix_buffer that is ready to be connected to a socket descriptor

Definition at line 1032 of file unix_buffer.H.

unix_buffer::unix_buffer	(	const int	_fd,
		const int	secs_timeout = 75
	)			[inline, explicit]

create an unix_buffer that is connected to the given socket descriptor

Parameters:

	_fd	descriptor of an already opened connection
	secs_timeout	(optional) timeout in seconds before read/write operations may fail

Remarks:

- connection will be closed on destruction

• if you want to reuse the descriptor, you should use the default constructor and attach a descriptor later on with autoclose set to false

Definition at line 1046 of file unix_buffer.H.

unix_buffer::unix_buffer

(

const connection_waiter &

cw

)

[inline, explicit]

create an unix_buffer that is connected to the given socket descriptor

Parameters:

cw

a connection_waiter object, that returns a descriptor of the next incoming client connection request

Remarks:

connection will automatically be closed on destruction

Definition at line 1057 of file unix_buffer.H.

unix_buffer::unix_buffer	(	const std::string &	host,
		const int	port
	)			[inline]

create an unix_buffer that connects to the given socket (and create a socket descriptor by itself)

Parameters:

	host	string of symbolic/numerical internet address of host to connect
	port	port number to connect

Definition at line 1069 of file unix_buffer.H.

virtual unix_buffer::~unix_buffer

(

)

[inline, virtual]

destroy the unix_buffer and close network connection (if any was open)

Definition at line 1214 of file unix_buffer.H.

Member Function Documentation

virtual int unix_buffer::_get_descriptor

(

)

const [inline, protected, virtual]

Reimplemented from unix_fd_buffer.

Definition at line 931 of file unix_buffer.H.

virtual int unix_buffer::empty_buffer

(

)

[inline, protected, virtual]

Reimplemented from unix_fd_buffer.

Definition at line 933 of file unix_buffer.H.

References unix_fd_buffer::buffersize, cerr, count(), endl(), errno, my_strerror(), unix_fd_buffer::obuffer, and PTHREAD_TESTCANCEL.

Here is the call graph for this function:

virtual int unix_buffer::underflow

(

)

[inline, protected, virtual]

Reimplemented from unix_fd_buffer.

Definition at line 976 of file unix_buffer.H.

References unix_fd_buffer::buffersize, count(), errno, unix_fd_buffer::ibuffer, my_strerror(), PTHREAD_TESTCANCEL, and unix_fd_buffer::pushbacksize.

Here is the call graph for this function:

virtual int unix_buffer::detach

(

)

[inline, virtual]

detach the buffer from the socket descriptor

Returns:

an open socket descriptor or -1 if there was no socket descriptor or it has been autoclosed

Remarks:

If returnvalue is not -1, it is most possibly open and should not be thrown away.

Reimplemented from unix_fd_buffer.
