| | 39 | Reads contents of a PE/COFF image.\r |
| | 40 | \r |
| | 41 | A function of this type reads contents of the PE/COFF image specified by FileHandle. The read \r |
| | 42 | operation copies ReadSize bytes from the PE/COFF image starting at byte offset FileOffset into \r |
| | 43 | the buffer specified by Buffer. The size of the buffer actually read is returned in ReadSize. \r |
| | 44 | If FileOffset specifies an offset past the end of the PE/COFF image, a ReadSize of 0 is returned.\r |
| | 45 | A function of this type must be registered in the ImageRead field of a PE_COFF_LOADER_IMAGE_CONTEXT \r |
| | 46 | structure for the PE/COFF Loader Library service to function correctly. This function abstracts access \r |
| | 47 | to a PE/COFF image so it can be implemented in an environment specific manner. For example, SEC and PEI \r |
| | 48 | environments may access memory directly to read the contents of a PE/COFF image, and DXE or UEFI \r |
| | 49 | environments may require protocol services to read the contents of PE/COFF image \r |
| | 50 | stored on FLASH, disk, or network devices.\r |
| | 51 | \r |
| | 52 | If FileHandle is not a valid handle, then ASSERT().\r |

| | 54 | If Buffer is NULL, then ASSERT().\r |
