safe_command_interpreter

In stock Circlemud the standard buffers are global variables, so functions using them are non returning (it isn't safe to call an ACMD within another ACMD).
I've coded a veeery simple (and maybe buggish, i can't compile on this PC) wrapper to command_interpreter, so it can be called from another ACMD.
Please mail me if you find any bugs, and if you find this little snippet useful.
Greetings from Italy!

void safe_command_interpreter(struct char_data *ch, char *argument)
{
	char * nbuf, nbuf1, nbuf2, narg;
	
	//frozing the old buffers
	nbuf = (char *)malloc(strlen(buf)+1);
	nbuf = strcpy(buf);
	buf = '\n';
	
	nbuf1 = (char *)malloc(strlen(buf1)+1);
	nbuf1 = strcpy(buf1);
	buf1 = '\n';
	
	nbuf2 = (char *)malloc(strlen(buf2)+1);
	nbuf2 = strcpy(buf2);
	buf2 = '\n';
	
	narg = (char *)malloc(strlen(arg)+1);
	narg = strcpy(arg);
	arg = '\n';
	
	command_interpreter(struct char_data *ch, char *argument);

	//put the old buffers in the microwave oven	
	buf = strcpy(nbuf);
	free(nbuf);
	
	buf1 = strcpy(nbuf1);
	free(nbuf1);
	
	buf2 = strcpy(nbuf2);
	free(nbuf2);
		
	arg = strcpy(narg);
	free(narg);
}
