Edition Manager Routines / Creating and Registering a Section

IsRegisteredSection

Upon receiving a section event, your application must call the IsRegisteredSection function to verify that the event received is for a registered section. You must call IsRegisteredSection before handling a section event because your application may have just called UnRegisterSection while the event was already being held in the event queue.

FUNCTION IsRegisteredSection (sectionH: SectionHandle): OSErr;

sectionH

A handle to the section record for a given section.

DESCRIPTION

The IsRegisteredSection function returns a result code (not a Boolean value) indicating whether the section is registered. A noErr result code indicates that a section is registered.

RESULT CODES

noErr	0	No error
notRegisteredSectionErr	-452	Not registered
