Detailed Description

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

       Note: Since this plugin is built on top of the Performance Marker Plugin, it is not
       possible to associate both plugins with a handle

       Stripe performace throughput callback

       This callback will be called with every performance callback that is received by the perf
       plugin. The first callback for each stripe_ndx will have an instantaneous_throughput based
       from the time the command was sent.

       This callback will be called with every performance callback that is received by the perf
       plugin. The first callback for will have an instantaneous_throughput based from the time
       the command was sent. This callback will be called after the per_stripe_cb

       Parameters:

       Transfer complete callback

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

       Parameters:
           handle The client handle associated with this transfer
           user_specific User argument passed to globus_ftp_client_throughput_plugin_init
           success indicates whether this transfer completed successfully or was interrupted (by
           error or abort)

   typedef void*(* globus_ftp_client_throughput_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_throughput_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_throughput_plugin_complete_cb_tcomplete_cb, void *user_specific)
       Throughput plugin init

       Use this function to initialize a throughput plugin. The throughput plugin sits on top of
       the perf_plugin. The only required param is 'plugin', all others may be GLOBUS_NULL

       Parameters:
           plugin a pointer to a plugin type to be initialized
           begin_cb the callback to be called upon the start of a transfer
           per_stripe_cb the callback to be called every time updated throughput info is
           available for a given stripe
           total_cb the callback to be called every time updated throughput info is available for
           any stripe
           complete_cb the callback to be called to indicate transfer completion
           user_specific a pointer to some user specific data that will be provided to all
           callbacks

       Returns:

           · GLOBUS_SUCCESS

           · Error on NULL plugin

           · Error on init perf plugin

       globus_ftp_client_throughput_plugin_user_destroy_cb_tdestroy_cb)
       Set user copy and destroy callbacks

       Use this to have the plugin make callbacks any time a copy of this plugin is being made.

       *plugin)
       Destroy throughput plugin

       Frees up memory associated with plugin.

       Returns:

           · GLOBUS_SUCCESS

       Retrieve user specific pointer.

       Parameters:
