kRTLoadSegbyNum and kRTLoadSegbyNumA5

This operation (available only for CFM-68K) allows you to explicitly load a segment by segment number. kRTLoadSegbyNum assumes the current A5 world, while kRTLoadSegbyNumA5 lets you specify one in the fA5 field of the RTPB structure (page B-2).

No user vectors are called while attempting to load the segment. If for any reason the segment cannot be loaded, the operation returns OSErr.

The fRTParams structure (page B-2) used with these operations is as follows:

struct RTLoadSegbyNumParam{
   short fSegNumber;
   };
typedef struct RTLoadSegbyNumParam RTLoadSegbyNumParam;

The fSegNumber field holds the specified segment number. If there is insufficient memory to load the segment, the GetResource call returns a Memory Manager error. If fSegNumber is not a valid segment number, GetResource also returns an error.
