Hi! I am trying to build a OpenIGTLink server based on Qt platform. It has two servers running on two threads respectively. The receiver server is used to receive image data from a software, and the sender server used to send the received image data to 3D Slicer.
The first problem is that, when my Qt server receive and send image data through the same server, it did. But when i receive the image data through receiver server, and send the data through sender server, the function
int s = senderSocket->Send(ImgMsg->GetPackPointer(), ImgMsg->GetPackSize());
which return 1, but there is not image data in 3D Slicer client.
The second problem is that when I run the code in Qt release mode, the compiler report the error
"HEAP[transfer_station.exe]: Heap block at 000001E22B9A3F10 modified at 000001E22B9A4034 past requested size of 114".
I use Visual Leak Detector to check, and the result print
"WARNING: Visual Leak Detector detected memory leaks!
---------- Block 2 at 0x000000005965FF00: 159 bytes ----------
Leak Hash: 0xC66716A5, Count: 1, Total 159 bytes
Call Stack (TID 25380):
ucrtbase.dll!malloc_base()
transfer_station.exe!igtl::Strnlen() + 0x3AA5 bytes
transfer_station.exe!igtl::HeaderOnlyMessageBase::CalculateContentBufferSize() + 0x2A2 bytes
transfer_station.exe!igtl::Strnlen() + 0x4166 bytes
KERNEL32.DLL!BaseThreadInitThunk() + 0x14 bytes
ntdll.dll!RtlUserThreadStart() + 0x21 bytes"
I dont know how to fix it. Could anyone help me? Thanks!
