Detailed Description

Globus Callback Function Interface.

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.

Backward compatible name

Typedef Documentation

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

Callback space handle.

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

Enumeration Type Documentation

Error types.
