Error-Handling Routines
| Routine | Use | .NET Framework equivalent |
|---|---|---|
| assert macro | Test for programming logic errors; available in both the release and debug versions of the run-time library | System::Diagnostics::Debug::Assert |
| _ASSERT, _ASSERTE macros | Similar to assert, but only available in the debug versions of the run-time library |
System::Diagnostics::Debug::Assert |
| clearerr | Reset error indicator. Calling rewind or closing a stream also resets the error indicator. |
Not applicable. To call the standard C function, use PInvoke. For more information, see Platform Invoke Examples. |
| _eof | Check for end of file in low-level I/O | Not applicable. To call the standard C function, use PInvoke. For more information, see Platform Invoke Examples. |
| feof | Test for end of file. End of file is also indicated when _read returns 0. |
Not applicable. To call the standard C function, use PInvoke. For more information, see Platform Invoke Examples. |
| ferror | Test for stream I/O errors | Not applicable. To call the standard C function, use PInvoke. For more information, see Platform Invoke Examples. |
| _RPT, _RPTF macros | Generate a report similar to printf, but only available in the debug versions of the run-time library |
Not applicable. To call the standard C function, use PInvoke. For more information, see Platform Invoke Examples. |
| _set_error_mode | Modifies __error_mode to determine a non-default location where the C run time writes an error message for an error that will possibly end the program. |
|
| _set_purecall_handler | Sets the handler for a pure virtual function call. |
