C++ (Cpp) LOAD32BE Examples

Example #1

File: tiff.c Project: BigHNF/tcpmp-revive

static NOINLINE int Read32(tiff* p)
{
	int v;
	if (p->BigEndian)
		v = LOAD32BE(p->Ptr);
	else
		v = LOAD32LE(p->Ptr);
	p->Ptr += 4;
	return v;
}

Example #2

File: dhcp_debug.c Project: frankzzcn/M2_SE_RTOS_Project

error_t dhcpDumpInt32(const DhcpOption *option)
{
   uint32_t value;

   //Check option length
   if(option->length != 4)
      return ERROR_INVALID_OPTION;

   //Retrieve 32-bit value
   value = LOAD32BE(option->value);
   //Dump option contents
   TRACE_DEBUG("    %" PRIu32 "\r\n", value);

   //No error to report
   return NO_ERROR;
