Exception on memcpy(). I want to send a message

Question

FILE * pFile = fopen("C:\\Penguins.jpg","rb");
fseek( pFile, 0, SEEK_END );
int Size = ftell( pFile );
fseek(pFile,0,SEEK_SET);
zmq::message_t newmessage ;
memcpy((void*)newmessage.data(),pFile,Size);
requester.send(newmessage);
fclose(pFile);

Memcpy() out with Access violation (parameters: 0x00000008). What to do? I tried a lot!

Answer 1

You will need to replace the memcpy with:

  fread((char *)(newmessage.data), 1, Size, pFile);

Answer 2

If you want to copy the file with memcpy, you need to memory map the file. Since you didn't memory map the file, you need to read it with, say, fread.
