Detailed Description

       The FTP Performance Marker plugin allows the user to obtain performance markers for all
       types of transfers except a third party transfer in which Extended Block mode is not
       enabled.

       These markers may be generated internally, or they may be received from a server ('put' or
       third_party_transfer' only).

       Copy constructor and destructor callbacks are also provided to allow one to more easily
       layer other plugins on top of this one.

Typedef Documentation

   typedef void(* globus_ftp_client_perf_plugin_begin_cb_t)(void *user_specific,
       globus_ftp_client_handle_t *handle, const char *source_url, const char *dest_url,
       globus_bool_t restart)
       Transfer begin callback

       This callback is called when a get, put, or third party transfer is started. Note that it
       is possible for this callback to be made multiple times before ever receiving the complete
       callback... this would be the case if a transfer was restarted. The 'restart' will
       indicate whether or not we have been restarted.

       Parameters:
           handle this the client handle that this transfer will be occurring on
           user_specific this is user specific data either created by the copy method, or, if a
           copy method was not specified, the value passed to init
           source_url source of the transfer (GLOBUS_NULL if 'put')
           dest_url dest of the transfer (GLOBUS_NULL if 'get')
           restart boolean indicating whether this callback is result of a restart

       Returns:

           • n/a

   typedef void(* globus_ftp_client_perf_plugin_marker_cb_t)(void *user_specific,
       globus_ftp_client_handle_t *handle, long time_stamp_int, char time_stamp_tength, int
       stripe_ndx, int num_stripes, globus_off_t nbytes)
       Performance marker received callback

       This callback is called for all types of transfers except a third party in which extended
       block mode is not used (because 112 perf markers wont be sent in that case). For extended
       mode 'put' and '3pt', actual 112 perf markers will be used and the frequency of this
       callback is dependent upon the frequency those messages are received. For 'put' in which
       extended block mode is not enabled and 'get' transfers, the information in this callback
       will be determined locally and the frequency of this callback will be at a maximum of one
       per second.

       Parameters:
           handle this the client handle that this transfer is occurring on
           user_specific this is user specific data either created by the copy method, or, if a
           copy method was not specified, the value passed to init
           time_stamp the timestamp at which the number of bytes is valid
           stripe_ndx the stripe index this data refers to
           num_stripes total number of stripes involved in this transfer
           nbytes the total bytes transfered on this stripe

       Returns:

           • n/a

   typedef void(* globus_ftp_client_perf_plugin_complete_cb_t)(void *user_specific,
       globus_ftp_client_handle_t *handle, globus_bool_t success)
       Transfer complete callback

       This callback will be called upon transfer completion (successful or otherwise)

       Parameters:
           handle this the client handle that this transfer was occurring on
           user_specific this is user specific data either created by the copy method, or, if a
           copy method was not specified, the value passed to init
           success indicates whether this transfer completed successfully or was interrupted (by
           error or abort)

       Returns:

           • n/a

   typedef void*(* globus_ftp_client_perf_plugin_user_copy_cb_t)(void *user_specific)
       Copy constructor

       This callback will be called when a copy of this plugin is made, it is intended to allow
       initialization of a new user_specific data.

       Parameters:
           user_specific this is user specific data either created by this copy method, or the
           value passed to init

       Returns:

           • a pointer to a user specific piece of data

           • GLOBUS_NULL (does not indicate error)

   typedef void(* globus_ftp_client_perf_plugin_user_destroy_cb_t)(void *user_specific)
       Destructor

       This callback will be called when a copy of this plugin is destroyed, it is intended to
       allow the user to free up any memory associated with the user specific data.

       Parameters:
           user_specific this is user specific data created by the copy method

       Returns:

           • n/a

       globus_ftp_client_perf_plugin_complete_cb_tcomplete_cb, void *user_specific)
       Initialize a perf plugin

       This function initializes a performance marker plugin. Any params except for the plugin
       may be GLOBUS_NULL

       Parameters:
           plugin a pointer to a plugin type to be initialized
           user_specific a pointer to some user specific data that will be provided to all
           callbacks
           begin_cb the callback to be called upon the start of a transfer
           marker_cb the callback to be called with every performance marker received
           complete_cb the callback to be called to indicate transfer completion

       Returns:

           • GLOBUS_SUCCESS

           • Error on NULL plugin
