Name
RaiseList Function
Syntax
function RaiseList: Pointer;
Description
The RaiseList
function returns a pointer to the
current exception frame, which might be the first node in a list of
exceptions. The System
unit does not declare the
type of the exception frame; the record is shown in the example.
The first frame in the list is the current exception. If an exception handler raises an exception, you can have multiple frames in the exception list.
RaiseList
is a real function.
Tips and Tricks
Usually, the
try
-except
statement provides the necessary functionality for handling exceptions. You shouldn’t need to callRaiseList
unless you are trying to handle exceptions in a non-standard way.Each thread has its own separate exception list.
Example
type
PRaiseFrame = ^TRaiseFrame;
TRaiseFrame = packed record
NextRaise: PRaiseFrame;
ExceptAddr: Pointer;
ExceptObject: TObject;
ExceptionRecord: PExceptionRecord; // Type defined in Windows unit.
end;
...
try
...
except
Code := PRaiseFrame(RaiseList).ExceptionRecord.ExceptionCode;
if Code = Exception_BreakPoint then
...
end;
