[Asterisk-Dev] Wait for Digits

[Dean Whitock]

I am wanting to modify the wait for digits command to accept 2 key 
presses instead of 1 but still have the time out

What would be the best way to do this ?



char ast_waitfordigit(struct ast_channel *c, int ms)
{
    /* XXX Should I be merged with waitfordigit_full XXX */
    struct ast_frame *f;
    char result = 0;
    /* Stop if we're a zombie or need a soft hangup */
    if (c->zombie || ast_check_hangup(c))
        return -1;
    /* Wait for a digit, no more than ms milliseconds total. */
    while(ms && !result) {
        ms = ast_waitfor(c, ms);
        if (ms < 0) /* Error */
            result = -1;
        else if (ms > 0) {
            /* Read something */
            f = ast_read(c);
            if (f) {
                if (f->frametype == AST_FRAME_DTMF)
                    result = f->subclass;
                ast_frfree(f);
            } else
                result = -1;
        }
    }
    return result;
}



Thanks,

Dean
