@CHIP-RTOS C Library V2.06 - BIOS API


BIOS_Set_Focus

Set STDIO focus.

void BIOS_Set_Focus ( IO_FOCUS focus );

Parameters

focus

Enumeration type:
    FOCUS_SHELL = 1: Set focus to command shell
    FOCUS_APPLICATION = 2: Set focus to application
    FOCUS_BOTH = 3: Set focus to both application and command shell

Comments

This function sets the focus of STDIO to either console, application or both.

If your application requires input from the user, you should set the focus to the application.   You should take care that only one application requests input from STDIO.

The user can change the focus by using the focus hot key (default Ctrl-F).   Changing the focus clears the serial input and output queues immediately.

Important :
    All buffered incoming and outgoing characters in the internal serial send and receive queues are lost after this call.

This function includes a one millisecond sleep.
