_set_app_type

An internal function used at startup to tell the CRT whether the app is a console app or a GUI app.

Syntax

typedef enum _crt_app_type
{
    _crt_unknown_app,
    _crt_console_app,
    _crt_gui_app
} _crt_app_type;

void __cdecl _set_app_type(
    _crt_app_type appType
    );

Parameters

appType
A value that indicates the application type. The possible values are:

Value	Description
_crt_unknown_app	Unknown application type.
_crt_console_app	Console (command-line) application.
_crt_gui_app	GUI (Windows) application.

Remarks

Normally, you don't need to call this function. It's part of the C runtime startup code that executes before main is called in your app.

By default, this function's global state is scoped to the application. To change this behavior, see Global state in the CRT.

Requirements

Routine	Required header
