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.
