The stream-open function

Your stream-open function must take the following steps:

1. Accept as its arguments the type-specific initialization information and use them to open the data.
2. Call mi_stream_init() with appropriate information to initialize an MI_STREAM structure (see Table 1).

The stream-open function must prepare the arguments for the call to the mi_stream_init() function, which initializes and optionally allocates an MI_STREAM structure. The mi_stream_init() function takes the following arguments:

• The stream-operations structure
• The stream data
• A stream descriptor
