| Routine Description:
 | |
| 
 | |
|   Support routine for the PE/COFF Loader that reads a buffer from a PE/COFF file
 | |
| 
 | |
| Arguments:
 | |
| 
 | |
|   FileHandle - The handle to the PE/COFF file
 | |
| 
 | |
|   FileOffset - The offset, in bytes, into the file to read
 | |
| 
 | |
|   ReadSize   - The number of bytes to read from the file starting at FileOffset
 | |
| 
 | |
|   Buffer     - A pointer to the buffer to read the data into.
 | |
| 
 | |
| Returns:
 | |
| 
 | |
|   EFI_SUCCESS - ReadSize bytes of data were read into Buffer from the PE/COFF file starting at FileOffset
