Typedef Documentation

typedef int globus_callback_handle_t

Handle for a periodic callback.

This handle can be copied or compared, and represented as NULL with GLOBUS_NULL_HANDLE

typedef int globus_callback_space_t

Handle for a callback space.

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

Handle for a space attr.

This handle can be copied and represented as NULL with GLOBUS_NULL
