发帖数: 116 | 1 The packet is something like
struct packet
{
unsigned int a;
unsigned int b;
....
};
The size of the struct differs between 32-bit and 64-bit system.
how can I make it the same size across different platforms?

guaranteed to be exactly that much wide.

systems
#pragma pack(1)
struct packet
{
unsigned int a;
unsigned int b;
....
};
This way compiler padding is disabled.
