GB_STREAM
typedef
struct GB_STREAM {
GB_STREAM_DESC *desc;
long _reserved;
long _free[6];
}
GB_STREAM;
If you create a class that inherits the
Stream class, then you must
declare your class structure this way:
typedef
struct {
GB_BASE object;
GB_STREAM stream;
}
MyClass;
The
_free array is a space where you can store data associated with the stream,
like the opened file descriptor for example.
Do not use this structure directly, but declares a specific stream structure having
the same size and beginning with the
GB_STREAM_DESC field and the
_reserved field.
The
desc field must points at a structure that points at the implementation functions of your stream.
Streams of the same type should share the same description structure. See
GB_STREAM_DESC
for more details.
