EAccessViolation Class

EAccessViolation is the exception class for invalid memory access errors.

Pascal

EAccessViolation = class(EExternal);

C++

class EAccessViolation : public EExternal;

EAccessViolation is raised when an application

Dereferences a nil (Delphi) or NULL (C++) pointer.

Writes to memory reserved for executable code.

Attempts to access a memory address for which there is no virtual memory allocated to the application.

Run-time exception information is saved in fields provided by EExternal.

Note: Applications should not raise EAccessViolation directly, but should instead rely on the runtime to raise this exception.
