|
JWSCL Documentation
|
|
|
function GetSizeMax(out cbSize: Largeint): HRESULT; stdcall;
|
Parameters |
Description |
|
out cbSize: Largeint |
Receives the number of bytes necessary to store the security descriptor in a stream |
This method can return several, among others, these error codes:
|
Value |
Description |
|
S_OK |
Successfully completed. Parameter cbSize contains the size. |
|
E_NOTIMPL |
The function is disabled due to setting property SupportIPersistStream to false. |
|
E_UNEXPECTED |
An exception occured that is not an EOleSysError exception. |
|
others |
There can be other errors coming from a EOleSysError. The value is the same as the value of the member ErrorCode of EOleSysError. |
This method behaves differently in a debug or release build. In a debug build an exception is returned to the caller. This can be useful in a debugging session.
GetSizeMax returns the maximum size necessary to store the security descriptor.
This method implements TJwServerAccessControl.GetSizeMax of IPersistStream.
Currently the function returns the actual size of the security descriptor.
