Function

Copy from extended into normal memory.

Header

em.h

Declaration

void __fastcall__ em_copyfrom (const struct em_copy* copy_data);

Description

Copy data from extended memory into linear memory. Source and target addresses as well as the number of bytes to transfer are specified in the em_copy structure that is passed as a parameter.

Limits

• Calling em_copyfrom will invalidate the memory window, so if you made any changes to the data in the window, call em_commit first, 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.
