SdlNet.SDLNet_Read32 Method 

Get a 32bit (a long on 32bit systems) value from the data buffer area which is in network byte order.

[Visual Basic]
Public Shared Function SDLNet_Read32( _
   ByVal area As IntPtr _
) As Integer
[C#]
public static int SDLNet_Read32(
   IntPtr area
);

Parameters

area
The pointer into a data buffer, at which to get the number from.

Remarks

This helps avoid byte order differences between two systems that are talking over the network. The returned value can be a signed number, the unsigned parameter type doesn't affect the data. The area pointer need not be at the beginning of a buffer, but must have at least 4 bytes of space left, including the byte currently pointed at.

Binds to C-function call in SDL_error.h:

extern DECLSPEC Uint32 SDLCALL SDLNet_Read32(void *area)

Example

            // get a number from a data buffer to use on this host
            //char *ptr; //this points into a previously received data buffer
            Uint32 number;
            number=SDLNet_Read32(ptr);
            // number is now in your hosts byte order, ready to use.
