*errmode.c - modify __error_mode and __app_type
|
|
*
|
|
* Copyright (c) 1994-2001, Microsoft Corporation. All rights reserved.
|
|
*
|
|
*Purpose:
|
|
* Defines _set_error_mode() and __set_app_type(), the routines used
|
|
* to modify __error_mode and __app_type variables. Together, these
|
|
* two variables determine how/where the C runtime writes error
|
|
* messages.
|
|
*
|
|
*Revision History:
|
|
* 09-06-94 GJF Module created.
|
|
* 01-16-95 CFW Set default debug output for console.
|
|
* 01-24-95 CFW Some debug name changes.
|
|
* 03-21-95 CFW Add _CRT_ASSERT report type.
|
|
* 07-07-95 CFW Simplify default report mode scheme.

/***
|
|
*int _set_error_mode(int modeval) - interface to change __error_mode
|
|
*
|
|
*Purpose:
|
|
* Control the error (output) sink by setting the value of __error_mode.
|
|
* Explicit controls are to direct output t o standard error (FILE * or
|
|
* C handle or NT HANDLE) or to use the MessageBox API. This routine is
|
|
* exposed and documented for the users.
|
|
*
|
|
*Entry:
|
|
* int modeval = _OUT_TO_DEFAULT, error sink is determined by __app_type
|
|
* _OUT_TO_STDERR, error sink is standard error
|
|
* _OUT_TO_MSGBOX, error sink is a message box
|
|
* _REPORT_ERRMODE, report the current __error_mode value
|
|
*
|
|
*Exit:
|
|
* Returns old setting or -1 if an error occurs.
