Function Documentation

globus_result_t globus_gass_copy_handle_init (globus_gass_copy_handle_t * handle, globus_gass_copy_handleattr_t * attr)

Initialize a GASS Copy handle. A globus_gass_copy_handle must be initialized before any transfers may be associated with it. This function initializes a globus_gass_copy_handle to be used for doing transfers, this includes initializing a globus_ftp_client_handle which will be used for doing any ftp/gsiftp transfers. The same handle may be used to perform multiple, consecutive transfers. However, there can only be one transfer associated with a particular handle at any given time. After all transfers to be associated with this handle have completed, the handle should be destroyed by calling globus_gass_copy_handle_destroy().

Parameters:

handle The handle to be initialized
attr The handle attributes used to use with this handle

Returns:

This function returns GLOBUS_SUCCESS if successful, or a globus_result_t indicating the error that occurred.

globus_gass_copy_handle_destroy() , globus_gass_copy_handleattr_init(), globus_ftp_client_hande_init()

References GLOBUS_GASS_COPY_MODULE.

globus_result_t globus_gass_copy_handle_destroy (globus_gass_copy_handle_t * handle)

Destroy a GASS Copy handle. Destroy a gass_copy_handle, which was initialized using globus_gass_copy_handle_init(), that will no longer be used for doing transfers. Once the handle is detroyed, no further transfers should be associated with it.

Parameters:

handle The handle to be destroyed

Returns:

This function returns GLOBUS_SUCCESS if successful, or a globus_result_t indicating the error that occurred.

globus_gass_copy_handle_init(), globus_ftp_client_handle_destroy()

References GLOBUS_GASS_COPY_MODULE.

globus_result_t globus_gass_copy_set_buffer_length (globus_gass_copy_handle_t * handle, int length)

Set the size of the buffer to be used for doing transfers. This function allows the user to set the size of the buffer that will be used for doing transfers, if this function is not called the buffer size will default to 1M.

Parameters:

handle Set the buffer length for transfers associated with this handle.
length The length, in bytes, to make the buffer.

Returns:

This function returns GLOBUS_SUCCESS if successful, or a globus_result_t indicating the error that occurred.

References GLOBUS_GASS_COPY_MODULE.

globus_result_t globus_gass_copy_get_buffer_length (globus_gass_copy_handle_t * handle, int * length)

Get the size of the buffer being used for doing transfers. This function allows the user to get the size of the buffer that is being used for doing transfers.

Parameters:

handle Get the buffer length for transfers associated with this handle.
length The length, in bytes, of the buffer.

Returns:

This function returns GLOBUS_SUCCESS if successful, or a globus_result_t indicating the error that occurred.

References GLOBUS_GASS_COPY_MODULE.

globus_result_t globus_gass_copy_set_no_third_party_transfers (globus_gass_copy_handle_t * handle, globus_bool_t no_third_party_transfers)

Turn third-party transfers on or off. (They are on by default.)

This function allows the user to turn third-party transfers on or off for ftp to ftp transfers associated with a particular handle. This is often desired if one of the servers involved in the transfer does not allow third-party transfers.

Parameters:

handle Turn third-party transfers on or off for transfers associated with this handle. They are on by default.
no_third_party_transfers GLOBUS_FALSE if third-party transfers should be used. GLOBUS_TRUE if third-party transfers should not be used.

Returns:

This function returns GLOBUS_SUCCESS if successful, or a globus_result_t indicating the error that occurred.

globus_result_t globus_gass_copy_get_no_third_party_transfers (globus_gass_copy_handle_t * handle, globus_bool_t * no_third_party_transfers)

See if third-party transfers are turned on or off. (They are on by default.)

This function allows the user to see if third-party transfers are turned on or off for ftp to ftp transfers associated with a particular handle. This is often desired if one of the servers involved in the transfer does not allow third-party transfers.

Parameters:

handle See if third-party transfers are turned on or off for transfers associated with this handle. They are on by default.
no_third_party_transfers GLOBUS_FALSE if third-party transfers should be used. GLOBUS_TRUE if third-party transfers should not be used.

Parameters:

handle Get the offsets for partial transfers associated with this handle.
offset The starting offset for the partial transfer.
end_offset The ending offset for the partial transfer.

Returns:

This function returns GLOBUS_SUCCESS if successful, or a globus_result_t indicating the error that occurred.

References GLOBUS_GASS_COPY_MODULE.

globus_result_t globus_gass_copy_attr_init (globus_gass_copy_attr_t * attr)

Initialize an attribute structure. The globus_gass_copy_attr_t can be used to pass the globus_gass_copy library information about how a transfer should be performed. It must first be initialized by calling this function. Then any or all of the following functions may be called to set attributes associated with a particular protocol: globus_gass_copy_attr_set_ftp(), globus_gass_copy_attr_set_gass(), globus_gass_copy_attr_set_io(). Any function which takes a globus_gass_copy_attr_t as an argument will also accept GLOBUS_NULL, in which case the appropriate set of default attributes will be used.

Parameters:

attr The attribute structure to be initialized

Returns:

This function returns GLOBUS_SUCCESS if successful, or a globus_result_t indicating the error that occurred.

globus_result_t globus_gass_copy_attr_set_ftp (globus_gass_copy_attr_t * attr, globus_ftp_client_operationattr_t * ftp_attr)

Set the attributes for ftp/gsiftp transfers. In order to specify attributes for ftp/gsiftp transfers, a globus_ftp_client_operationattr_t should be initialized and its values set using the appropriate globus_ftp_client_operationattr_* functions. The globus_ftp_client_operationattr_t * can then be passed to the globus_gass_copy_attr_t via this function.

Parameters:

attr A globus_gass_copy attribute structure
ftp_attr The ftp/gsiftp attributes to be used

Returns:

This function returns GLOBUS_SUCCESS if successful, or a globus_result_t indicating the error that occurred.

globus_result_t globus_gass_copy_attr_set_io (globus_gass_copy_attr_t * attr, globus_io_attr_t * io_attr)

Set the attributes for file transfers. In order to specify attributes for file transfers, a globus_io_attr_t should be initialized and its values set using the appropriate globus_io_attr_* functions. The globus_io_attr_t can then be passed to the globus_gass_copy_attr_t via this function.

Parameters:

Set the attributes for http/https transfers. In order to specify attributes for http/https transfers, a globus_gass_transfer_requestattr_t should be initialized and its values set using the appropriate globus_gass_transfer_requestattr_* functions. The globus_gass_transfer_requestattr_t can then be passed to the globus_gass_copy_attr_t via this function.
