globus_result_tglobus_ftp_client_operationattr_set_mode(globus_ftp_client_operationattr_t*attr,globus_ftp_control_mode_tmode)
Set/Get the file transfer mode attribute for an ftp client attribute set.
This attribute allows the user to choose the data channel protocol used to transfer a file. There are two
modes supported by this library: stream mode and extended block mode.
Stream mode is a file transfer mode where all data is sent over a single TCP socket, without any data
framing. In stream mode, data will arrive in sequential order. This mode is supported by nearly all FTP
servers.
Extended block mode is a file transfer mode where data can be sent over multiple parallel connections and
to multiple data storage nodes to provide a high-performance data transfer. In extended block mode, data
may arrive out-of-order. ASCII type files are not supported in extended block mode.
Parametersattr The attribute set to query or modify.
mode The value of mode attribute
Seealsoglobus_ftp_client_operationattr_set_parallelism(), globus_ftp_client_operationattr_set_layout()Note
Extended block mode is a Grid-FTP extension, and may not be supported on all FTP servers.
globus_result_tglobus_ftp_client_operationattr_set_net_stack(globus_ftp_client_operationattr_t*attr,constchar*driver_list)
Set/Get the gridftp xio driver stack used for the data channel.
This attribute allows the user to control which xio drivers will be used for data transport. The driver
MUST be installed and allowed by the server or the transfer/get/put will result in an error.
Parametersattr The attribute set to query or modify.
driver_list driver list in the following format: driver1[:driver1opts][,driver2[:driver2opts]][...].
The string 'default' will reset the stack list to the server default.

globus_result_tglobus_ftp_client_operationattr_set_parallelism(globus_ftp_client_operationattr_t*attr,constglobus_ftp_control_parallelism_t*parallelism)
Set/Get the parallelism attribute for an ftp client attribute set.
This attribute allows the user to control the level of parallelism to be used on an extended block mode
file transfer. Currently, only a 'fixed' parallelism level is supported. This is interpreted by the FTP
server as the number of parallel data connections to be allowed for each stripe of data. Currently, only
the 'fixed' parallelism type is
This attribute is ignored in stream mode.
Parametersattr The attribute set to query or modify.
parallelism The value of parallelism attribute.
Seealsoglobus_ftp_client_operationattr_set_layout(), globus_ftp_client_operationattr_set_mode()Note
This is a Grid-FTP extension, and may not be supported on all FTP servers.
globus_result_tglobus_ftp_client_operationattr_set_read_all(globus_ftp_client_operationattr_t*attr,globus_bool_tread_all,globus_ftp_client_data_callback_tintermediate_callback,void*intermediate_callback_arg)
Set/Get the read_all attribute for an ftp client attribute set.
This attribute allows the user to pass in a single buffer to receive all of the data for the current
transfer. This buffer must be large enough to hold all of the data for the transfer. Only one buffer may
be registered with globus_ftp_client_register_read() when this attribute is used for a get.
In extended block mode, this attribute will cause data to be stored directly into the buffer from
multiple streams without any extra data copies.
If the user sets the intermediate callback to a non-null value, this function will be called whenever an
intermediate sub-section of the data is received into the buffer.
This attribute is ignored for globus_ftp_client_put() or globus_ftp_client_third_party_transfer()
operations.
Parametersattr The attribute set to query or modify.
read_all The value of read_all attribute.
intermediate_callback Callback to be invoked when a subsection of the data has been retreived. This
callback may be GLOBUS_NULL, if the user only wants to be notified when the data transfer is
completed.
intermediate_callback_arg User data to be passed to the intermediate callback function.
globus_result_tglobus_ftp_client_operationattr_set_storage_module(globus_ftp_client_operationattr_t*attr,constchar*module_name,constchar*module_args)
Set/Get the gridftp storage module (DSI).
This attribute allows the user to control what backend module they use with the gridftp server. The
module MUST be implemented by the server or the transfer/get/put will result in an error.
This attribute is ignored in stream mode.
Parametersattr The attribute set to query or modify.
module_name The backend storage module name
module_args The backend storage module parameters
Note
This is a Grid-FTP extension, and may not be supported on all FTP servers.
globus_result_tglobus_ftp_client_operationattr_set_striped(globus_ftp_client_operationattr_t*attr,globus_bool_tstriped)
Set/Get the striped attribute for an ftp client attribute set.
This attribute allows the user to force the client library to used the FTP commands to do a striped data
transfer, even when the user has not requested a specific file layout via the layout attribute. This is
useful when transferring files between servers which use the server side processing commands ERET or ESTO
to transform data and send it to particular stripes on the destination server.
The layout attribute is used only when the data is being stored the server (on a put or 3rd party
transfer). This attribute is ignored for stream mode data transfers.
Parametersattr The attribute set to query or modify.
striped The value of striped attribute.
Seealsoglobus_ftp_client_operationattr_set_parallelism(), globus_ftp_client_operationattr_set_layout()globus_ftp_client_operationattr_set_mode()Note

globus_result_tglobus_ftp_client_operationattr_set_tcp_buffer(globus_ftp_client_operationattr_t*attr,constglobus_ftp_control_tcpbuffer_t*tcp_buffer)
Set/Get the TCP buffer attribute for an ftp client attribute set.
This attribute allows the user to control the TCP buffer size used for all data channels used in a file
transfer. The size of the TCP buffer can make a significant impact on the performance of a file transfer.
The user may set the buffer to either a system-dependent default value, or to a fixed value.
The actual implementation of this attribute is designed to be as widely interoperable as possible. In
addition to supporting the SBUF command described in the GridFTP protocol extensions document, it also
supports other commands and site commands which are used by other servers to set TCP buffer sizes. These
are
• SITE RETRBUFSIZE
• SITE RBUFSZ
• SITE RBUFSIZ
• SITE STORBUFIZE
• SITE SBUFSZ
• SITE SBUFSIZ
• SITE BUFSIZE
This attribute is affects any type of data transfer done with the ftp client library.
Parametersattr The attribute set to query or modify.
tcp_buffer The value of tcp_buffer attribute.
globus_result_tglobus_ftp_client_operationattr_set_type(globus_ftp_client_operationattr_t*attr,globus_ftp_control_type_ttype)
Set/Get the file representation type attribute for an ftp client attribute set.
This attribute allows the user to choose the file type used for an FTP file transfer. The file may be
transferred as either ASCII or a binary image.
When transferring an ASCII file, the data will be transformed in the following way
• the high-order bit will be set to zero
• end-of line characters will be converted to a CRLF pair for the data transfer, and then converted to
native format before being returned to the user's data callbacks.
The default type for the ftp client library is binary.
Parametersattr The attribute set to query or modify.
type The value of type attribute.
