Return the following: rc The return code - 0 = PASS, 1 = FAIL. shell_rc The shell return code returned by process_plug_in_packages.py. failed_plug_in_name The failed plug in name (if any). Description of arguments: plug_in_packages_list A python list of plug-in directory paths. call_point The call point program to be called for each plug-in package (e.g. post_boot). This name should not include the "cp_" prefix. shell_rc The user may supply a value other than zero to indicate an acceptable non-zero return code. For example, if this value equals 0x00000200, it means that for each plug-in call point that runs, a 0x00000200 will not be counted as a failure. stop_on_plug_in_failure If this parameter is set to 1, this program will stop and return non-zero if the call point program from any plug-in directory fails. Conversely, if it is set to false, this program will run the call point program from each and every plug-in directory regardless of their return values. Typical example cases where you'd want to run all plug-in call points regardless of success or failure would be "cleanup" or "ffdc" call points. stop_on_non_zero_rc If this parm is set to 1 and a plug-in call point program returns a valid non-zero return code (see "shell_rc" parm above), this program will stop processing and return 0 (success). Since this constitutes a successful exit, this would normally be used where the caller wishes to stop processing if one of the plug-in directory call point programs returns a special value indicating that some special case has been found. An example might be in calling some kind of "check_errl" call point program. Such a call point program might return a 2 (i.e. 0x00000200) to indicate that a given error log entry was found in an "ignore" list and is therefore to be ignored. That being the case, no other "check_errl" call point program would need to be called. release_type The type of release being tested (e.g. "obmc", "op", "fips"). This influences which integrated plug-ins are selected. quiet If quiet is set to 1, this function will NOT write status messages to stdout. This will default to the global quiet program parm or to 0. debug If this parameter is set to 1, this function will print additional debug information. This is mainly to be used by the developer of this function. This will default to the global quiet program parm or to 0.
