SPOOLCONTROLBUF Procedure

The SPOOLCONTROLBUF procedure is used to perform device-dependent I/O

operations requiring a data buffer when the application process is spooling at level 3.

This procedure must be used in place of CONTROLBUF if a level-3 buffer is specified

in a call to SPOOLSTART.

error-code returned value

INT

returns one of the following spooler error codes:

level-3-buff input, output

INT:ref:512

is the level-3-buff specified in the SPOOLSTART procedure.

operation input

INT:value

is a SPOOLCONTROLBUF operation as follows:

buffer input

INT:ref:*

error-code := SPOOLCONTROLBUF ( level-3-buff ! i,o

,operation ! i

,buffer ! i

,count ! i

,[bytes-written-to-buff] ! o

,[extended-level-3-buff] ); ! i,o

0 Successful operation

%1000-%1377 Error on file to collector (bits <8:15> contain a file-system error

number; see Considerations on page 4-27)

%10000 Missing parameter

%10001 Parameter is present, but its content is wrong

%11000 Checkpoint exit

%11001 Attempted to write to the collector without first opening the file
