_com_raise_error
Microsoft Specific
Throws a _com_error in response to a failure.
Syntax
void __stdcall _com_raise_error(
HRESULT hr,
IErrorInfo* perrinfo = 0
);
Parameters
hr
HRESULT information.
perrinfo
IErrorInfo
object.
Remarks
_com_raise_error, which is defined in <comdef.h>, can be replaced by a user-written version of the same name and prototype. This could be done if you want to use #import
but do not want to use C++ exception handling. In that case, a user version of _com_raise_error might decide to do a longjmp
or display a message box and halt. The user version should not return, though, because the compiler COM support code does not expect it to return.
You can also use _set_com_error_handler to replace the default error-handling function.
By default, _com_raise_error is defined as follows:
void __stdcall _com_raise_error(HRESULT hr, IErrorInfo* perrinfo) {
throw _com_error(hr, perrinfo);
}
