Routine Description:
This routine logically opens an encapsulated sub-file within the KEY file.
Currently, file handles are implemented as simply ResID indicies.
Thus, "opening" a file simply involves looking up its ResID.
Arguments:
FileName - Supplies the name of the resource file to open.
Type - Supplies the type of file to open (i.e. ResTRN, ResARE).
Return Value:
The routine returns a new file handle on success. The file handle must be
closed by a call to CloseFile on successful return.
On failure, the routine returns the manifest constant INVALID_FILE, which
should not be closed.
Environment:
User mode.
