Prepare an extended memory page for use.
void* __fastcall__ em_use (unsigned page);
The function maps one page of extended memory into linear memory and returns a pointer to the page frame. This function is similar to
em_map, but will not transfer data into the actual memory window in the assumption that the existing data is wrong or will get overwritten.
em_usewill invalidate the memory window, so if you made any changes to the data in the window, call
em_commitfirst, or the changes are lost.
- The function is only available as fastcall function, so it may only be used in presence of a prototype.
- The function produces undefined results if no extended memory driver is loaded.
