Remove coercion handler

#include <AppleEvents.h> Apple Event Manager

OSErr AERemoveCoercionHandler ( fromType, toType, handler,

isSysHandler );

DescType fromType ; descriptor type of coerced data

DescType toType ; descriptor type of resulting data

ProcPtr handler ; pointer to coercion handler routine

Boolean isSysHandler ; TRUE = removed from system coercion table

FALSE = removed from application coercion table

returns Error Code; 0 = no error

The AERemoveCoercionHandler function removes a coercion handler

routine from either the application or system coercion table.

The fromType parameter is the descriptor type of the data coerced by the

handler.

The toType parameter is the descriptor type of the resulting data.

The handler parameter is a pointer to the coercion handler routine. Although

the fromType and toType parameters would be sufficient to identify the

handler to be removed, providing the handler parameter is a safeguard to

ensure that you remove the correct handler.

The isSysHandler parameter specifies the coercion table from which to

remove the handler. If its value is TRUE, the handler is removed from the

system coercion table. If its value is FALSE, the handler is removed from the

application coercion table.

Result codes

noErr (0) No error

memFullErr (-108) Not enough room in heap zone

errAEHandlerNotFound (-1717) No coercion handler found
