Syntax

VOID Metainit( metainfo )
METAINFO *metainfo;

Function      Metainit() returns information regarding the current version
              and installed drives of MetaDOS.

Opcode        48 (0x30)

Availability  To test for the availability of MetaDOS the following steps
              must be taken:
              1. Fill the METAINFO structure with all zeros.
              2. Call Metainit().
              3. If metainfo.version is NULL, MetaDOS is not installed.

Parameters    metainfo is a pointer to a METAINFO structure which is
              filled in by the call. METAINFO is defined as:

              typedef struct
              {
               /* Bitmap of drives (Bit 0 = A, 1 = B, etc... */
               ULONG drivemap;

               /* String containing name and version */
               char *version;

               /* Currently unused */
               LONG reserved[2];
              } METAINFO;
