Macro Definition Documentation

   #define GLOBUS_CALLBACK_MODULE
       Module descriptor. Module descriptor for for globus_callback module. Must be activated
       before any of the following api is called.

       Note: You would not normally activate this module directly. Activating the
       GLOBUS_COMMON_MODULE will in turn activate this also.

   #define GLOBUS_POLL_MODULE
       Module descriptor.

       Deprecated

       Backward compatible name

Typedef Documentation

   typedef int globus_callback_handle_t
       Periodic callback handle. This handle can be copied or compared, and represented as NULL
       with GLOBUS_NULL_HANDLE

   typedef struct globus_l_callback_space_attr_s* globus_callback_space_attr_t
       Callback space attribute. This handle can be copied and represented as NULL with
       GLOBUS_NULL

   typedef int globus_callback_space_t
       Callback space handle. This handle can be copied or compared and represented as NULL with
       GLOBUS_NULL_HANDLE

Enumeration Type Documentation

   enum globus_callback_error_type_t
       Error types. Possible error types returned by the api in this module. You can use the
       error API to check results against these types.
