    It specifies the number of bits used by the struct member (only possible within structs).

    Example: (copied from MSDN help).

    Code:
    struct CELL             // Declare CELL bit field
    {
       unsigned character  : 8;  // 00000000 ????????
       unsigned foreground : 3;  // 00000??? 00000000
       unsigned intensity  : 1;  // 0000?000 00000000
       unsigned background : 3;  // 0???0000 00000000
       unsigned blink      : 1;  // ?0000000 00000000
    };

    Ok, I guessed it was something like that. But I did'nt know that it could only be used within structs.

    Thanks and sorry for not reading the manual.
