globus_result_t globus_xio_attr_cntl (attr, driver, GLOBUS_XIO_ORDERING_GET_BUF_SIZE, int * buf_size_out)¶

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Get the size of the buffer used for the internal reads.

Parameters

globus_result_t globus_xio_attr_cntl (attr, driver, GLOBUS_XIO_ORDERING_GET_BUFFERING, globus_bool_t * buffering_out)¶

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Get the buffering flag on the attr.

Parameters

globus_result_t globus_xio_attr_cntl (attr, driver, GLOBUS_XIO_ORDERING_GET_MAX_BUF_COUNT, int * max_buf_count_out)¶

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Get the maximum buffer count set on the attr.

Parameters

globus_result_t globus_xio_attr_cntl (attr, driver, GLOBUS_XIO_ORDERING_GET_MAX_READ_COUNT, int * max_read_count_out)¶

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Get the maximum number of parallel reads set on the attr.

Parameters

globus_result_t globus_xio_attr_cntl (attr, driver, GLOBUS_XIO_ORDERING_SET_BUF_SIZE, int buf_size)¶

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Set the size of the buffer that ordering driver creates to use for reading data from the driver below it.

Parameters

globus_result_t globus_xio_attr_cntl (attr, driver, GLOBUS_XIO_ORDERING_SET_BUFFERING, globus_bool_t buffering)¶

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. This driver can be used in 2 modes; ordering (care about offsets of the data read - underlying transport driver may deliver data out of order - this driver will rearrange data based on the offset and deliver inorder to user) and buffering (do not care about offsets - just buffer the data read abd deliver it when requested). This attribute control can be used to enable buffering.

Parameters

globus_result_t globus_xio_attr_cntl (attr, driver, GLOBUS_XIO_ORDERING_SET_MAX_BUF_COUNT, int max_buf_count)¶

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Set the maximum number of buffers that this driver can create for reading data from the driver below it.

Parameters

globus_result_t globus_xio_attr_cntl (attr, driver, GLOBUS_XIO_ORDERING_SET_MAX_READ_COUNT, int max_read_count)¶

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Set the maximum number of reads that ordering driver can have outstanding on driver(s) below.

Parameters

globus_result_t globus_xio_handle_cntl (handle, driver, GLOBUS_XIO_ORDERING_SET_OFFSET, globus_off_t offset)¶

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Set offset for the next IO operation. This is not allowed when there is an outstanding IO operation. This operation clears all the buffered data.
