unsupported function (extension not found)

Notes

• The null-terminated string specifies the host-specific vendor name or some other unique identifier to obtain a specific extension entry point. The string comparison used to look up the API entry point is case-sensitive.

• Clients must use a FAR CALL to reach the extended API entry point.

• All extended API parameters are specified by the vendor.

• DPMI 1.0 clients should use Int 2FH Function 168AH in preference to this function. DPMI 1.0 hosts support this function solely for backward compatibility with DPMI 0.9 clients.
