Member Function Documentation

Send()

int XrdXrootdTransSend::Send ( const struct iovec *  headP, int  headN, const struct iovec *  tailP, int  tailN  )

virtual

Complete a File() callback.

The Send() method must be called after the File() callback is invoked to complete data transmission using sendfile(). If Send() is not called the pending sendfile() call is not made and no data is sent to the client.

Parameters

headP	a pointer to the iovec structure containing the data that must be sent before the sendfile() data. If there is none, the pointer can be null.
headN	the number of elements in the headP iovec structure array.
tailP	a pointer to the iovec structure containing the data that must be sent after the sendfile() data. If there is none, the pointer can be null.
tailN	the number of elements in the tailP iovec structure array.

Returns

< 0 transmission error has occurred. This can be due to either connection failure or data source error (i.e. I/O error). = 0 data has been successfully sent. > 0 the supplied context was not generated by a valid File() callback. No data has been sent.

Parameters

headP	pointer to leading data array
headN	array count
tailP	pointer to trailing data array
tailN	array count
