Albeu:

I have done it as you said, and lets say it is kinda working.. But it doesn't do exactly as I imagined it would.

I want that my read function writes the command (nevermind if it is
hardoced, it is to be fixed later on) to for example mutes the player

Should it be done something like in the code below... (I don't know how
to write or in what format to write the command to its destination?)

I'm looking at the code from lirc.c which has this at the begining:

int mp_input_lirc_read(int fd,char* dest, int s) {
fd_set fds;
struct timeval tv;
int r,cl = 0;
char *code = NULL,*c = NULL;
// We have something in the buffer return it
	if(cmd_buf != NULL) {
	int l = strlen(cmd_buf), w = l > s ? s : l;
	memcpy(dest,cmd_buf,w);
	l -= w;
	if(l > 0)
	memmove(cmd_buf,&cmd_buf[w],l+1);
	else {
		free(cmd_buf);
		cmd_buf = NULL;
	}
	return w;
}
