SetADBInfo

SetADBInfo Establish a device's service routine address and data area address

#include <DeskBus.h> ADB Manager

OSErr SetADBInfo(info, ADBAddr );

ADBSetInfoBlock *info ; address of parameter block

ADBAddress ADBAddr ; value identifying device table index

returns Error Code ; 0=no error

Use SetADBInfo to establish a device's service routine address and data area

address in the device table.

info is a parameter block whose relevant fields are:

-> siServiceRtPtr Ptr 4 0 Pointer to a service routine

-> siDataAreaAddr Ptr 4 4 Pointer to a data area

ADBAddr is the index number on the device table of the entry being queried.

Returns: an operating system Error Code.

noErr (0) No error

Notes: Send the Flush command to the device after you call this procedure as a

way of keeping it from sending old data to the new data area address.

Apple Tech Note 206 points out that just by using SetADBInfo to install a

service routine for the appropriate address you can add devices to the bus

without having to call the ADBReInit procedure and all the bugs associated

with it.
