Error Handling (CRT)

Use these routines to handle program errors.

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.
