ImageRead function that operates on a memory buffer whos base is passed into Reads contents of a PE/COFF image from a buffer in system memory.
FileHandle.
This is the default implementation of a PE_COFF_LOADER_READ_FILE function
that assumes FileHandle pointer to the beginning of a PE/COFF image.
This function reads contents of the PE/COFF image that starts at the system memory
address specified by FileHandle. The read operation copies ReadSize bytes from the
PE/COFF image starting at byte offset FileOffset into the buffer specified by Buffer.
The size of the buffer actually read is returned in ReadSize.
If FileHandle is NULL, then ASSERT().
If ReadSize is NULL, then ASSERT().
If Buffer is NULL, then ASSERT().
@param FileHandle Ponter to baes of the input stream @param FileHandle Pointer to base of the input stream
@param FileOffset Offset to the start of the buffer @param FileOffset Offset into the PE/COFF image to begin the read operation.
@param ReadSize Number of bytes to copy into the buffer @param ReadSize On input, the size in bytes of the requested read operation.
