AEManagerInfo

You can use the AEManagerInfo function to obtain information about the version of the Apple Event Manager currently available or the number of processes that are currently recording Apple events. This function is available only in version 1.01 and later versions of the Apple Event Manager.

FUNCTION AEManagerInfo (keyword: AEKeyword; 
                        VAR result: LongInt): OSErr;

keyword

A value that determines what kind of information AEManagerInfo returns. The value can be represented by one of these constants:

CONST keyAERecorderCount = 'recr';
keyAEVersion = 'vers';

result

If the value of the keyword parameter is keyAERecorderCount, this parameter is an integer that indicates the number of processes that are currently recording Apple events. If the value of the keyword parameter is keyAEVersion, this parameter is an integer that provides information about the version of the Apple Event Manager available on the current computer, using the same format as a 'vers' resource.

RESULT CODE
