Register 15 contains a return code indicating
the success or failure of the request. Possible return codes (in decimal)
are:
- 0
- The environment was activated and the routine called.
- 4
- The function code is not valid.
- 8
- CEEPIPI was called from a Language Environment-conforming HLL.
- 12
- The indicated environment was initialized for main routines. No routine was executed.
- 16
- The token is not valid.
- 28
- The enclave was terminated but the process level persists.
This value indicates the enclave was terminated while the process was retained. This can occur due to a STOP or EXIT statement (or an exit() function) being issued or due to an unhandled condition. The sub_ret_code, sub_reason_code, and sub_feedback_code indicate this action.
- 40
- The subprogram was an XPLINK program and the preinitialized environment is non-XPLINK. This is not valid.
- 41
- Indicates the routine address could not be converted to a function descriptor.
