Guardian Procedure Calls Reference Manual

FCBs by using the CHECK^FILE procedure. For additional about SIO procedures, see the
Guardian Programmer's Guide.
• Assign and param messages
Except when invoked by the backup process of a process pair, INITIALIZER reads the startup
message, then optionally requests assign and param messages (see flags.<11>. For each
assign message, the FCBs (if rucb is passed) are searched for a logical file name matching
the logical file name contained in the assign message. If a match is found, the information
from the assign message is put into the file's FCBs, and the match count is incremented.
For proper matching of names, the "progname" and "filename" fields of the assign message
must be blank-padded.
Note that you can perform your own processing of these messages using startupproc,
assignproc, and paramproc irrespective of whether you use FCBs.
• Calls to ABEND
INITIALIZER calls the ABEND procedure for any errors it detects. If INITIALIZER does call
ABEND, text describing the cause of the call is passed in the process deletion (ABEND) system
message. The possible causes are:
◦ Timeout reading $RECEIVE.
◦ Invalid value specified for the timelimit parameter.
◦ Unable to open $RECEIVE.
◦ Unable to obtain process handle.
◦ Unexpected message from the creator process.
◦ In the backup process of a process pair, CHECKMONITOR returned and bit 12 of flags
was equal to zero.
◦ The number of FCBs specified in ALLOCATE^CBS, ALLOCATE^CBS^D00, or num^fcbs
is incorrect, or the format of an FCB is invalid.
For further information about the text that is passed in the process deletion (ABEND) system
message, see "INITIALIZER Errors" in the Guardian Procedure Errors and Messages Manual.
• FCBs and native mode
In native mode, you must use the num^fcbs and fcb^array parameters to explicitly reference
any FCBs that INITIALIZER modifies, for example, using file names supplied in the Startup,
ASSIGN, or PARAM messages.
