Slot Manager Routines
routines take one parameter: a pointer to a Slot Manager parameter block. Each routine description includes a list of the fields affected by that routine.
Each field in the list is preceded by an arrow that indicates how the field is
used.
Arrow Meaning
Æ You provide the value of the parameter as input to the
function has completed execution.
´ You provide a value for the parameter, and the Slot Manager returns another value.
For a general description of the parameter block, see the separate section,
Slot Parameter Block.
You can use the SVersion function to determine the version of the Slot Manager available to your program. These routines can be used by applications as well as by device drivers. You can use the routines described in
Enabling and Disabling SResource Data Structures under the section
or to restore sResource data structures deleted from the Slot Resource Table.
These routines are intended primarily for use by device drivers.
Assembly-language note: You can use an assembly- language
assembly-language macro for a routine has the same name as the
high-level language routine, except that the name is preceded by an
underscore. However, these macros do not directly invoke the trap
mechanism. Instead, each of these macros places a routine selector in
the D0 register and calls the trap macro _SlotManager.
Place a pointer to the Slot Manager parameter block in the A0 register when you call each Slot Manager routine in assembly language. Each routine returns with the status result in the low-order word of the D0 register.
