CEEGQDT—Retrieve q_data_token
CEEGQDT retrieves the q_data_token from the Instance-Specific Information (ISI). CEEGQDT is particularly useful when you have user-written condition handlers registered by CEEHDLR.
Syntax >>-CEEGQDT--(--cond_rep--,--q_data_token--,--fc--)-------------><
- cond_rep (input)
- A condition token defining the condition for which the q_data_token is retrieved.
- q_data_token (output)
- A pointer to the q_data associated with condition token cond_rep.
- fc (output)
- A 12-byte feedback code, optional in some languages,
that indicates the result of this service. If you choose to omit this
parameter, refer to Invoking callable services for the
appropriate syntax to indicate that the feedback code was omitted.
The following symbolic conditions can result from this service.
Code Severity Message number Message text CEE000 0 — The service completed successfully. CEE0EE 3 0462 Instance-specific information for the condition token with message number message-number and facility ID facility-id could not be found. CEE0EG 3 0464 Instance-specific information for the condition token with message number message-number and facility ID facility-id did not exist.
Usage notes
- z/OS UNIX consideration—In multithread applications, CEEGQDT affects only the calling thread.
