Detailed Description

       Net Manager Context Management Functions.

       The Net Manager Context manages a collection of network manager plug-ins which will be
       called when network events occur.

       Initialize the context by calling globus_net_manager_context_init(). This processes an
       array of attributes. The 'scope' member of of attributes indicate the name of a network
       manager to associate with the context. The (name, value) tuples of the attributes are
       added to the attributes passed to all of that particular network manager's implementation
       functions.

       Once the network manager context is created, pass it to the per-operation invocation
       functions to trigger all of the manager callouts associated with the context.

       When the network manager context is no longer needed, destroy it by calling
       globus_net_manager_context_destroy().

Typedef Documentation

   typedef struct globus_i_net_manager_context_s* globus_net_manager_context_t
       Net Manager Context. A structure of this type is used to thread attributes through the set
       of configured net manager modules and invoke their functions in configuration order.

Function Documentation

   void globus_net_manager_context_destroy (globus_net_manager_context_t context)
       Destroy Context. This functions destroys context.

       Parameters
           context Pointer to the context to destroy.

   globus_result_t globus_net_manager_context_end_listen (globus_net_manager_context_t context,
       const char * task_id, const char * transport, const char * local_contact, const
       globus_net_manager_attr_t * attr_array)
       Call Context End Listen. Call the chain of end_listen() functions in a context with the
       given task_id, transport, and attributes. If any manager in the context returns an error,
       the subsequent managers will not be called.

       Parameters
           context The context to call functions in.
           task_id The task_id associated with this network operation.
           transport The transport driver associated with this network operation.
           local_contact The string representation of the local address of the socket.
           attr_array The set of attributes to pass to the managers.

       Returns
           On success, this function returns GLOBUS_SUCCESS. If any manager returns an error, the
           end_listen calls stop and the error is returned to the caller.

   globus_result_t globus_net_manager_context_init (globus_net_manager_context_t * context, const
       globus_net_manager_attr_t * attrs)
       Initialize Context. This functions initializes context with the attribute list attrs.

       Parameters
           context A pointer to the context to initialize.
           attrs An array of attributes to initialize the context with.

       Returns
           On error, the 'context' is set to NULL and this function returns an error object.
           Otherwise this function returns 'GLOBUS_SUCCESS'

   globus_result_t globus_net_manager_context_post_accept (globus_net_manager_context_t context,
       const char * task_id, const char * transport, const char * local_contact, const char *
       remote_contact, const globus_net_manager_attr_t * attr_array, globus_net_manager_attr_t **
       attr_array_out)
       Call Context Post Accept. Call the chain of post_accept() functions in a context with the
       given task_id, transport, contact information, and attributes. If any manager in the
       context returns an error, the subsequent managers will not be called. The attributes are
       chained through all the calls, with any changed values returned from a manager passed to
       subsequent managers in the chain.

       Parameters
           context The context to call functions in.
           task_id The task_id associated with this network operation.
           transport The transport driver associated with this network operation.
           local_contact The string representation of the local address of the socket.
           remote_contact The string representation of the remote address of the socket.
           attr_array The set of attributes to pass to the managers.
           attr_array_out The resulting set of attributes from the managers. This will be set to
           NULL if no manager modifies the attributes.

       Returns
           On success, this function returns GLOBUS_SUCCESS. If any manager returns an error, the
           post_accept calls stop and the error is returned to the caller.

       Call Context Post Close. Call the chain of post_close() functions in a context with the
       given task_id, transport, contact information, and attributes. If any manager in the
