Detailed Description

Initiate an FTP operation.

This module contains the API functions for a user to request a get, put, third-party transfer, or other FTP file operation.

Typedef Documentation

typedef void(* globus_ftp_client_complete_callback_t)(void *user_arg, globus_ftp_client_handle_t *handle, globus_object_t *error)

Operation complete callback. Every FTP Client operation (get, put, transfer, mkdir, etc) is asynchronous. A callback of this type is passed to each of the operation function calls to let the user know when the operation is complete. The completion callback is called only once per operation, after all other callbacks for the operation have returned.

Parameters:

user_arg The user_arg parameter passed to the operation.
handle The handle on which the operation was done.
error A Globus error object indicating any problem which occurred, or GLOBUS_SUCCESS, if the operation completed successfully.

Function Documentation

globus_result_t globus_ftp_client_exists (globus_ftp_client_handle_t * u_handle, const char * url, globus_ftp_client_operationattr_t * attr, globus_ftp_client_complete_callback_t complete_callback, void * callback_arg)

Check for the existence of a file or directory on an FTP server. This function attempts to determine whether the specified URL points to a valid file or directory. The complete_callback will be invoked with the result of the existence check passed as a globus error object, or GLOBUS_SUCCESS.

Parameters:

u_handle An FTP Client handle to use for the existence check operation.
url The URL of the directory or file to check. The URL may be an ftp or gsiftp URL.
attr Attributes to use for this operation.
complete_callback Callback to be invoked once the existence operation is completed.
callback_arg Argument to be passed to the complete_callback.

Returns:

This function returns an error when any of these conditions are true:

• u_handle is GLOBUS_NULL
• url is GLOBUS_NULL
• url cannot be parsed
• url is not a ftp or gsiftp url
• complete_callback is GLOBUS_NULL
• handle already has an operation in progress

globus_result_t globus_ftp_client_features_init (globus_ftp_client_features_t * u_features)

Initialize the feature set, to be later used by globus_ftp_client_feat(). Each feature gets initial value GLOBUS_FTP_CLIENT_MAYBE.

Note:

Structure initialized by this function must be destroyed using globus_ftp_client_features_destroy()

Returns:

GLOBUS_SUCCESS on success, otherwise error.

globus_result_t globus_ftp_client_features_destroy (globus_ftp_client_features_t * u_features)

Destroy the feature set. Note:

Structure passed to this function must have been previously initialized by globus_ftp_client_features_init().

Returns:

GLOBUS_SUCCESS on success, otherwise error.

globus_result_t globus_ftp_client_feat (globus_ftp_client_handle_t * u_handle, char * url, globus_ftp_client_operationattr_t * attr, globus_ftp_client_features_t * u_features, globus_ftp_client_complete_callback_t complete_callback, void * callback_arg)

Check the features supported by the server (FTP FEAT command). After this procedure completes, the features set (parameter u_features) represents the features supported by the server. Prior to calling this procedure, the structure should have been initialized by globus_ftp_client_features_init(); afterwards, it should be destroyed by globus_ftp_client_features_destroy(). After globus_ftp_client_feat() returns, each feature in the list has one of the values: GLOBUS_FTP_CLIENT_TRUE, GLOBUS_FTP_CLIENT_FALSE, or GLOBUS_FTP_CLIENT_MAYBE. The first two denote the server supporting, or not supporting, the given feature. The last one means that the test has not been performed. This is not necessarily caused by error; there might have been no reason to check for this particular feature.

Parameters:

u_handle An FTP Client handle to use for the list operation.
url The URL to list. The URL may be an ftp or gsiftp URL.
attr Attributes for this file transfer.
u_features A pointer to a globus_ftp_client_features_t to be filled with the feature set supported by the server.
complete_callback Callback to be invoked once the size check is completed.
callback_arg Argument to be passed to the complete_callback.

Returns:

This function returns an error when any of these conditions are true:

• u_handle is GLOBUS_NULL
• source_url is GLOBUS_NULL
• source_url cannot be parsed
• source_url is not a ftp or gsiftp url
• u_features is GLOBUS_NULL or badly initialized
• complete_callback is GLOBUS_NULL
• handle already has an operation in progress

Check if the feature is supported by the server. After the function completes, parameter answer contains the state of the server support of the given function. It can have one of the values: GLOBUS_FTP_CLIENT_TRUE, GLOBUS_FTP_CLIENT_FALSE, or GLOBUS_FTP_CLIENT_MAYBE.

Parameters:

u_features list of features, as returned by globus_ftp_client_feat()

Get a file from an FTP server. This function starts a 'get' file transfer from an FTP server. If this function returns GLOBUS_SUCCESS, then the user may immediately begin calling globus_ftp_client_register_read() to retrieve the data associated with this URL.

When all of the data associated with this URL is retrieved, and all of the data callbacks have been called, or if the get request is aborted, the complete_callback will be invoked with the final status of the get.

Parameters:

handle An FTP Client handle to use for the get operation.
url The URL to download. The URL may be an ftp or gsiftp URL.
attr Attributes for this file transfer.
restart Pointer to a restart marker.
partial_offset Starting offset for a partial file get.
partial_end_offset Ending offset for a partial file get. Use -1 for EOF.
complete_callback Callback to be invoked once the 'get' is completed.
callback_arg Argument to be passed to the complete_callback.

Returns:

This function returns an error when any of these conditions are true:

• handle is GLOBUS_NULL
• url is GLOBUS_NULL
• url cannot be parsed
• url is not a ftp or gsiftp url
• complete_callback is GLOBUS_NULL
• handle already has an operation in progress

globus_result_t globus_ftp_client_extended_get (globus_ftp_client_handle_t * handle, const char * url, globus_ftp_client_operationattr_t * attr, globus_ftp_client_restart_marker_t * restart, const char * eret_alg_str, globus_ftp_client_complete_callback_t complete_callback, void * callback_arg)

Get a file from an FTP server with server-side processing. This function starts a 'get' file transfer from an FTP server. If this function returns GLOBUS_SUCCESS, then the user may immediately begin calling globus_ftp_client_register_read() to retrieve the data associated with this URL.

When all of the data associated with this URL is retrieved, and all of the data callbacks have been called, or if the get request is aborted, the complete_callback will be invoked with the final status of the get.

This function differs from the globus_ftp_client_get() function by allowing the user to invoke server-side data processing algorithms. GridFTP servers may support support algorithms for data reduction or other customized data storage requirements. There is no client-side verification done on the algorithm string provided by the user. If the server does not understand the requested algorithm, the transfer will fail.

Parameters:

handle An FTP Client handle to use for the get operation.
url The URL to download. The URL may be an ftp or gsiftp URL.
attr Attributes for this file transfer.
restart Pointer to a restart marker.
eret_alg_str The ERET algorithm string. This string contains information needed to invoke a server-specific data reduction algorithm on the file being retrieved.
complete_callback Callback to be invoked once the 'get' is completed.
callback_arg Argument to be passed to the complete_callback.

Returns:

This function returns an error when any of these conditions are true:

• handle is GLOBUS_NULL
• url is GLOBUS_NULL
• url cannot be parsed
• url is not a ftp or gsiftp url
• complete_callback is GLOBUS_NULL
• handle already has an operation in progress

Store a file on an FTP server. This function starts a 'put' file transfer to an FTP server. If this function returns GLOBUS_SUCCESS, then the user may immediately begin calling globus_ftp_client_register_write() to send the data associated with this URL.

When all of the data associated with this URL is sent, and all of the data callbacks have been called, or if the put request is aborted, the complete_callback will be invoked with the final status of the put.

Parameters:

handle An FTP Client handle to use for the put operation.
url The URL to store the data to. The URL may be an ftp or gsiftp URL.
attr Attributes for this file transfer.
