Hi,

folgender Code:

#define SOMI(x) #x,
  ...
  #define SCENE_OBJECT_INTERNAL_MSG_CODES \
    SOIM(rotate_clockwise = 0)\
    SOIM(rotate_counterclockwise)\
    SOIM(move_left)\
    SOIM(move_right)
    ...

   typedef enum { SCENE_OBJECT_INTERNAL_MSG_CODES
               SCENE_OBJECT_USER_MSG_CODES             
             } so_msg_code_type;

dann...

static char 	message_buffer[5000]; 				
so_msg_code_type message_code;

was passiert aber hier?

message_code = *(so_msg_code_type *) message_buffer;

oder wenn ich sowas habe dann

so_msg_code_type *p_so_msg;

dann...

p_so_msg = (so_msg_code_type *)msg_buf;

Setze ich die Zeiger auf den Anfang des Buffers...?
