Description
EExternal is the exception class that captures external error information. {{#multireplace:System.SysUtils.EStackOverflow|H21=!|H25=%|H28=(|H29=)|H2A=*|H2B=+|H2F=/|H3C=<|H3D==|H3E=>|H5B=[|H5D=]|H5E=^|H7C=|}} inherits from {{#multireplace:System.SysUtils.EExternal|H21=!|H25=%|H28=(|H29=)|H2A=*|H2B=+|H2F=/|H3C=<|H3D==|H3E=>|H5B=[|H5D=]|H5E=^|H7C=|}}. All content below this line refers to {{#multireplace:System.SysUtils.EExternal|H21=!|H25=%|H28=(|H29=)|H2A=*|H2B=+|H2F=/|H3C=<|H3D==|H3E=>|H5B=[|H5D=]|H5E=^|H7C=|}}.
EExternal is the exception class that captures external error information.
EExternal is the ancestor of all exception classes that represent external run-time errors.
Note: EExternal classes represent Win32 exception codes. The ExceptionRecord member points to a Win32 exception record:
type
PExceptionRecord = ^TExceptionRecord;
TExceptionRecord = record
ExceptionCode: Cardinal;
ExceptionFlags: Cardinal;
ExceptionRecord: PExceptionRecord;
ExceptionAddress: Pointer;
NumberParameters: Cardinal;
ExceptionInformation: array[0..14] of Cardinal;
end;
var ExceptionRecord: PExceptionRecord;
struct TExceptionRecord;
typedef TExceptionRecord *PExceptionRecord;
struct TExceptionRecord
{
unsigned ExceptionCode;
unsigned ExceptionFlags;
TExceptionRecord *ExceptionRecord;
void *ExceptionAddress;
unsigned NumberParameters;
unsigned ExceptionInformation[15];
};
Note: Under MAC OS, EExternal classes represent various run-time errors. EExternal has three fields with exception information:
ExceptionAddress, which contains the address of the instruction that caused the error.AccessAddress, the address that was being accessed when the error occurred.SignalNumber, for exceptions raised by Macintosh signals.
