Detailed Description

Globus Callback Function Interface.

Define 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.

Enumerator:

GLOBUS_CALLBACK_ERROR_INVALID_CALLBACK_HANDLE	The callback handle is not valid or it has already been destroyed
GLOBUS_CALLBACK_ERROR_INVALID_SPACE	The space handle is not valid or it has already been destroyed
GLOBUS_CALLBACK_ERROR_MEMORY_ALLOC	Could not allocate memory for an internal structure
GLOBUS_CALLBACK_ERROR_INVALID_ARGUMENT	One of the arguments is NULL or out of range
GLOBUS_CALLBACK_ERROR_ALREADY_CANCELED	Attempt to unregister callback again
GLOBUS_CALLBACK_ERROR_NO_ACTIVE_CALLBACK	Attempt to retrieve info about a callback not in callers's stack
