SdlNet.SDLNet_Read16 Method
Get a 16bit (a short on 32bit systems) value from the data buffer area which is in network byte order.
[Visual Basic]
Public Shared Function SDLNet_Read16( _
ByVal
area As
IntPtr _
) As
Short
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 2 bytes of space left, including the byte currently pointed at.
Binds to C-function call in SDL_error.h:
extern DECLSPEC Uint16 SDLCALL SDLNet_Read16(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
Sint16 number;
number=(Sint16) SDLNet_Read16(ptr);
// number is now in your hosts byte order, ready to use.
