42 | @param This Indicates the calling context\r | |
43 | @param SectionType Pointer to an EFI_SECTION_TYPE. If SectionType == NULL,\r | |

56 | indicates the size in bytes of the memory region pointed to by Buffer. On output,\r | |
61c244aa | 57 | *BufferSize contains the number of bytes required to read the section.\r |
