DESCRIPTION

The SDeleteSRTRec function deletes an sResource from the slot resource table. This routine is typically called by a card's PrimaryInit code to delete any sResources that are not appropriate for the system as configured.

SPECIAL CONSIDERATIONS

The SDeleteSRTRec function is available only with Manager. You can use the SVersion function, described on page 2-30, to determine whether the Slot Manager is version 1 or later.

ASSEMBLY-LANGUAGE INFORMATION

The trap macro and routine selector for the SDeleteSRTRec function are

Trap macro	Selector

You must set up register D0 with the routine selector and register A0 with the address of the Slot Manager parameter block. When _SlotManager returns, register D0 contains the result code.
