class	QoreFtpClient

Detailed Description

provides access to sockets using Qore data structures

QoreSocket objects also have a QoreEncoding associated with them used for sending and receiving string data. String data received from the socket will be tagged with the appropriate encoding; string data send through the socket will be implicitly converted to the socket's encoding if necessary. This class does no implement any thread locking; thread locking must be performed at a higher level (for example, as with QoreHTTPClient and QoreFtpClient).

Note

currently only supports IPv4, TCP sockets

Member Function Documentation

accept() [1/2]

DLLEXPORT QoreSocket* QoreSocket::accept	(	SocketSource *	source,
		ExceptionSink *	xsink
	)

accepts a new connection on a listening socket and returns a new QoreSocket object for the new connection

the socket must be opened and in a listening state before making this call.

Parameters

source	source connection information will be written to this object if not 0
xsink	if an error occurs, the Qore-language exception information will be added here

Returns

a new QoreSocket object for the new connection (or 0 if an error occured)

• QoreSocket::acceptSSL()
• SocketSource

accept() [2/2]

DLLEXPORT QoreSocket* QoreSocket::accept	(	int	timeout_ms,
		ExceptionSink *	xsink
	)

accepts a new connection on a listening socket and returns a new QoreSocket object for the new connection with a timeout; if no connection is accepted within the timeout period 0 is returned

the socket must be opened and in a listening state before making this call.

Parameters

timeout_ms	the timeout in milliseconds; if a timeout occurs then 0 is returned (no Qore-language excepton is raised)
xsink	if an error occurs, the Qore-language exception information will be added here

Returns

a new QoreSocket object for the new connection (or 0 if an error or timeout occured)

returns 1 if the event was satisfied in the timeout period, 0 if not (= timeout), or -1 in case of an error (see errno in this case)

Parameters

timeout_ms	timeout in milliseconds, -1=never timeout, 0=do not block, return immediately if there is no data waiting
read	wait for data to be available for reading from the socket
write	wait for data to be written on the socket

See also

Note

This is a low-level socket function, if an SSL connection is in progress, then this function could return 1 for reading due to SSL protocol renegotiation for example. The socket buffer is ignored for this call (unlike isDataAvaialble())

i	the integer to write to the file
timeout_ms	the maximum amount of time the socket can block on a single send as an integer in milliseconds
xsink	if an error occurs in socket communication, the Qore-language exception information will be added here

Returns

0 for OK, not 0 if an error occured

QoreSocket::sendi8LSB()

sendi8LSB() [1/2]

DLLEXPORT int QoreSocket::sendi8LSB

(

int64

i

)

sends an 8-byte (64bit) binary integer in LSB (Least Significant Byte first, little endian) format through a connected socket

The socket must be connected before this call is made.

Note

that this is not network byte order, normally QoreSocket::sendi8() should be used

Parameters

i	the integer to write to the file

Returns

0 for OK, not 0 if an error occured

QoreSocket::sendi8()

sendi8LSB() [2/2]

DLLEXPORT int QoreSocket::sendi8LSB	(	int64	i,
		int	timeout_ms,
		ExceptionSink *	xsink
	)

sends an 8-byte (64bit) binary integer in LSB (Least Significant Byte first, little endian) format through a connected socket

The socket must be connected before this call is made.

Note

that this is not network byte order, normally QoreSocket::sendi8() should be used

Parameters

i	the integer to write to the file
timeout_ms	the maximum amount of time the socket can block on a single send as an integer in milliseconds
xsink	if an error occurs in socket communication, the Qore-language exception information will be added here

Returns

0 for OK, not 0 if an error occured

setEncoding()

DLLEXPORT void QoreSocket::setEncoding

(

const QoreEncoding *

id

)

sets the character encoding for strings sent and received with this socket

Parameters

id	the character encoding for strings sent and received with this socket

setSslVerifyMode()

DLLEXPORT void QoreSocket::setSslVerifyMode

(

int

mode

)

sets the SSL verification mode

If no SSL connection is in place, then the mode is saved for use with future SSL connections.

Parameters

mode	see the mode parameter of SSL_set_verify() for details

Since

Qore 0.8.13

shutdown()

DLLEXPORT int QoreSocket::shutdown

(

)

calls shutdown on the socket

shuts down the socket for reading and writing, after this call further sends and receives are disallowed until the socket is reopened.

Note

QoreSocket::shutdown() should normally be called before calling this function.

Returns

0 if OK, not 0 on error

See also

QoreSocket::shutdown()

shutdownSSL()

DLLEXPORT int QoreSocket::shutdownSSL

(

ExceptionSink *

xsink

)

shuts down an active SSL connection

called implicitly by QoreSocket::close()

Returns

0 if OK, not 0 on error

QoreSocket::close()

upgradeClientToSSL() [1/2]

DLLEXPORT int QoreSocket::upgradeClientToSSL	(	X509 *	cert,
		EVP_PKEY *	pkey,
		ExceptionSink *	xsink
	)

negotiates an SSL connection from the client side

The socket must be connected before this call is made.

Parameters

cert	the X509 certificate to use for the connection, may be 0 if no certificate should be used
pkey	the private key to use for the connection, may be 0 if no private key should be used
xsink	if an error occurs, the Qore-language exception information will be added here

Returns

0 if OK, not 0 on error

upgradeClientToSSL() [2/2]

DLLEXPORT int QoreSocket::upgradeClientToSSL	(	X509 *	cert,
		EVP_PKEY *	pkey,
		int	timeout_ms,
		ExceptionSink *	xsink
	)

negotiates an SSL connection from the client side

The socket must be connected before this call is made.

Parameters

cert	the X509 certificate to use for the connection, may be 0 if no certificate should be used

timeout_ms	timeout in milliseconds, -1 = never timeout
xsink	if an error occurs, the Qore-language exception information will be added here

Returns

0 if OK, not 0 on error
