Typedef Documentation
typedef void(* globus_ftp_control_auth_callback_t) (void *callback_arg, struct globus_ftp_control_handle_s *handle, globus_object_t *error, globus_ftp_control_auth_info_t *auth_result)
Server authentication complete callback.
A function with this signature is registered by calling globus_ftp_control_accept(). It is called when the authentication protocol has completed. Based on the auth_result, the server implementor should determine authorization and then send the appropriate response using globus_ftp_control_send_response(), indicating to the client whether authorization was successful or not.
Parameters
handle This structure is populated when the callback is called and represents a control connection to the client.
error Indicates if a command was successfully read or or if a failure occurred. This object will be freed once this callback returns. If the user wishes to have a copy of the error that persists past the life of this callback, they must make a copy using globus_object_copy(), and free it with globus_object_free().
auth_result A globus_ftp_control_auth_result_t containing the values the client sent for gss authentication, user name, password and account. If any of the values were not sent by the client they will be NULL. Based on that information the user can decide if the client will be authorized for use of the server.
callback_arg The user argument passed to the callback.
typedef struct globus_ftp_control_auth_info_s globus_ftp_control_auth_info_t
Authentication Values. This structure is populated and passed back to the user via the globus_ftp_control_auth_callback_t(). It contains the information needed to decide if a client may use the server.
typedef unsigned long globus_ftp_control_auth_requirements_t
Authentication requirements.

typedef void(* globus_ftp_control_callback_t) (void *callback_arg, struct globus_ftp_control_handle_s *handle, globus_object_t *error)
Asynchronous control callback.
This callback is used as a generic control operation callback.
Parameters
callback_arg User supplied argument to the callback function
handle A pointer to the GridFTP control handle. Used to identify which control connection the operation was applied to.
error Pointer to a globus error object containing information about any errors that occurred processing the operation
typedef void(* globus_ftp_control_command_callback_t) (void *callback_arg, struct globus_ftp_control_handle_s *handle, globus_object_t *error, union globus_ftp_control_command_u *command)
Server command callback.
When a command from a client is received on the control channel a user callback with this signature is called.
Parameters
callback_arg The user argument passed to the callback function.
handle The control handle that the command was issued on.
error Indicates if a command was successfully read or or if a failure occurred. This object will be freed once this callback returns. If the user wishes to have a copy of the error that persists past the life of this callback, they must make a copy using globus_object_copy(), and free it with globus_object_free().
command The command structure indicates what type of command the client issued. Based on the 'type' further information can be extracted. This command structure will be freed once this callback returns. If the user wishes to have a copy of the error that persists past the life of this callback, they must make a copy using globus_ftp_control_command_copy(), and free it with globus_ftp_control_command_free().
typedef void(* globus_ftp_control_data_callback_t) (void *callback_arg, globus_ftp_control_handle_t *handle, globus_object_t *error, globus_byte_t *buffer, globus_size_t length, globus_off_t offset, globus_bool_t eof)
Asynchronous data transmission operation callback.
This callback is called in functions that send or receive data on the data channel(s).
In the case of a write, this function is invoked when the entire data buffer is sent. Depending on the data transfer properties set by the globus_ftp_control_local_*() functions, the data may actually be split into multiple buffers and sent to multiple data nodes.
In the case of a read, this function will return a single extent of the data. The order of the data returned is not defined in an extended block mode data transfer, unless the ordered_data flag is set. It is up to the user of the API to re-construct the file order.
Parameters
callback_arg User supplied argument to the callback function
handle A pointer to the GridFTP control handle. Used to identify which control connection the operation was applied to.
error Pointer to a globus error object containing information about any errors that occurred processing the operation
buffer The user buffer passed as a parameter to globus_ftp_control_data_read() or globus_ftp_control_data_write().
length The amount of data in the buffer. In the case of an incoming data channel, this may be less than the buffer size.
offset The file offset of the data which is contained in the buffer.
eof This is set to GLOBUS_TRUE then all of the data associated with the transfer has arrived on the data connections associated with this handle. If multiple data callbacks are registered with this handle, there is no guaranteed order of the EOF callback with respect to other data callbacks. If multiple callbacks are registered when EOF is reached on the data connections, at least one callback function will be called with eof set to GLOBUS_TRUE.

typedef void(* globus_ftp_control_response_callback_t) (void *callback_arg, struct globus_ftp_control_handle_s *handle, globus_object_t *error, globus_ftp_control_response_t *ftp_response)
Asynchronous operation completion callback.
This callback is called whenever a reply to command is received on the FTP control channel. It allows the user to handle the received reply or alternatively handle any errors that occurred during the interaction with the FTP server. This function will be called multiple times in the case when intermediate responses (1yz) are received.
Parameters
callback_arg User supplied argument to the callback function
handle A pointer to the GridFTP control handle. Used to identify which control connection the operation was applied to.
error Pointer to a globus error object containing information about any errors that occurred processing the operation
ftp_response Pointer to a response structure containing the FTP response to the command.
