Sets the echo mode.

Syntax

int SetEcho(
  int echomode
);

Parameters

echomode

[in] Specifies the echo mode state.

Value	Description
OFF	Switches the echo mode off.
ON	Switches the echo mode on.
CURRENT_MODE	Does not change echo mode, but returns the current echo mode.

Return value

Returns the changed echo mode.

Remarks

When echo mode is on, the character is automatically displayed on the screen after a key press, without having to use putchar() or printf(). Note however, that the getchar() or kbhit() function must be called to display the character.
Only SetKeyinputMode(ORIGINAL_SHIFT_MODE) is supported.

Sample

#include <stdio.h>
#include "lib.h"
void readln( char *string)
{
    int c,x;

    ResetKey();
    for (x = 0 ;;)
    {
        switch( c = getchar() )
        {
        case EOF:
            Idle();
            break;

        case ENT_KEY:
            string[x] = '0';
            return;

        case BS_KEY:
            if( x != 0)
            {
                x--;
                string[x] = '0';
                printf("\r%s ", string);
                GotoXY( x, WhereY());
            }
            break;

        default:
            if( (c >= ' ') && (c < 0x80) && (x < 16))
                string[x++] = (char)c;
            break;
        }
    }
}
