Is the size of C “int” 2 bytes or 4 bytes?
...t the standard unsigned int requires (at least) sixteen bits of storage:
UINT_MAX 65535 // 2¹⁶ - 1
Thus we can see that unsigned int require (at least) 16 bits, which is where you get the two bytes (assuming CHAR_BIT is 8)... and later when that limit increased...
How do I safely pass objects, especially STL objects, to and from a DLL?
...very basic datatype, so that int will automatically be wrapped to int32_t, uint will be wrapped to uint32_t, etc. This all occurs behind the scenes, thanks to the overloaded = and () operators. I have omitted the rest of the basic type specializations since they're almost entirely the same except fo...

Just make sure that the characters in the string adhere to ...
