SPOOLCONTROL Procedure

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

when the application process is spooling at level 3.

If a level-3 buffer is specified in a call to SPOOLSTART, the SPOOLCONTROL

procedure must be used in place of the CONTROL procedure.

is a CONTROL operation value (see the CONTROL procedure in the Guardian

Procedure Calls Reference Manual for information about CONTROL operations).

param input
