Return codes

When the CSRSI service returns control to the caller, Returncode contains the return code. To obtain the equates for the return codes:

If you are coding in assembler, include mapping macro CSRSIIDF, described in z/OS MVS Data Areas in the z/OS Internet library.
If you are coding in C, use include file CSRSIC.

The following table describes the return codes, shown in decimal.

Return Code and Equate Symbol	Meaning and Action
00 (0) CSRSI_SUCCESS	Meaning: The CSRSI service completed successfully. All information requested was returned. Action: Check the si00validityflags field to determine the validity of each returned area.
04 (4) CSRSI_STSINOTAVAILABLE	Meaning: The CSRSI service completed successfully, but since the Store System Information (STSI) instruction was not available, only the SI00PCCACPID, SI00PCCACPUA, and SI00PCCACAFM fields are valid. Action: None required.
08 (8) CSRSI_SERVICENOTAVAILABLE	Meaning: Environmental error: The CSRSI service is not available on this system. Action: Avoid calling the CSRSI service unless running on a system on which it is available.
12 (C) CSRSI_BADREQUEST	Meaning: User error: The request parameter did not specify a word formed from any combination of CSRSI_Request_V1CPC_Machine, CSRSI_Request_V2CPC_LPAR, and CSRSI_Request_V3CPC_VM. Action: Correct the parameter.
16 (10) CSRSI_BADINFOAREALEN	Meaning: User error: The Infoarealen parameter did not match the length of the area required to return the requested information. Action: Correct the parameter.
20 (14) CSRSI_BADLOCK	Meaning: User error: The service was called while holding a system lock other than CPU, LOCAL/CML, or CMS. Action: Avoid calling in this environment.
