In Windows Embedded CE6 VirtualCopy is only callable from kernel-space. The function OEM_VirtualCopy is a workaround to use VirtualCopy from user-space.
This function dynamically maps a virtual address to a physical address by creating a new page-table entry.
See Platform-Builder-Help for details.
BOOL OEM_VirtualCopy( LPVOID lpvDest, LPVOID lpvSrc, DWORD cbSize, DWORD fdwProtect );
Parameters
lpvDest
Pointer to the destination memory that must be reserved.
lpvSrc
Pointer to committed memory.
cbSize
Size, in bytes, of the region. The allocated pages include all pages containing 1 or more bytes in the range from lpAddress to lpAddress plus cbSize. This means that a 2-byte range straddling a page boundary causes both pages to be included in the allocated region.
fdwProtect
Type of access protection
Return Values
TRUE indicates success FALSE indicates failure.
