[mod.computers.vax] Question on a Vax System Call Sch$Qast

OC.LEE@CU20B.COLUMBIA.EDU.UUCP (02/27/87)

Hi,

Can anyone tell me where I can find more information about this
system call, "SCH$QAST", it is for queuing asynchronous system traps.

This is a reposting of an earlier plea.

	Thanking all in advance,
	Tim

Information is available in the fiche.  Check SYS.MAP to find out which
module.  Whats wrong with SYS$DCLAST?  Well, here's the information
I pulled out of the fiche when writing some interrupt code.

	SCH$QAST:
	Inputs:	R2   Priority increment class
		R4   Pointer to PCB
		R5   Pointer to ACB

	Output: R0   Status

If executing at elevated IPL (Above IPL$FORK) I would suggest FORKing.
