C++ (Cpp) _sendrec Examples

Example #1

File: mppid.c Project: kasiajanocha/shell

int msysc(int who, int syscallnr,message* msgptr) {
	int status;

  msgptr->m_type = syscallnr;
  status = _sendrec(who, msgptr);
  if (status != 0) {
	msgptr->m_type = status;
  }
  if (msgptr->m_type < 0) {
	errno = -msgptr->m_type;
	return(-1);
  }
  return(msgptr->m_type);	
}

Example #2

File: mfork.c Project: pitex/minix-shell

int mfork(void) {
	message msg;
	register message * ptr = &msg;
	int status;

	ptr->m_type = 2;
	status = _sendrec(0, &msg);
	if (status != 0) {
		ptr->m_type = status;
	}
	if (ptr->m_type < 0) {
		errno = -ptr->m_type;
		return(-1);
	}
	return(ptr->m_type);
}

Example #3

File: syscall.c Project: DragonQuan/minix3

int _syscall(endpoint_t who, int syscallnr, message *msgptr)
{
  int status;

  msgptr->m_type = syscallnr;
  status = _sendrec(who, msgptr);
  if (status != 0) {
	/* 'sendrec' itself failed. */
	/* XXX - strerror doesn't know all the codes */
	msgptr->m_type = status;
  }
  if (msgptr->m_type < 0) {
	errno = -msgptr->m_type;
	return(-1);
  }
  return(msgptr->m_type);
}

Example #4

File: mppid.c Project: pitex/minix-shell

int mgetppid(void){
	message msg;
	register message * ptr = &msg;
	int status;

	ptr->m_type = 20;
	status = _sendrec(0, &msg);
	if (status != 0) {

	}
	if (ptr->m_type < 0) {
		errno = -ptr->m_type;
		return(-1);
	}
	
	if (ptr->m_type < 0) return ( (pid_t) -1);
	return( (pid.t) ptr->m2_i1);
