==== ReadEntryMetaRecords ====
−
Takes a type-6 output buffer, each entry being 0x10-byte bytes, a u32 entryoffset and a 0x10-sized entry. Returns a u32 for total_read_entries.
+
Takes a type-6 [[NCA#Meta_records|Meta Record]] output buffer, a u32 eoffset into that buffer, and an input [[NCA#Meta_records|Meta Record]] entry. Returns a u32 for total_read_entries.
   −
The input entry is the output entry from [[#GetTitleIdInfo]] starting at the TID. The output 0x10-bytes entries are the same as the output from [[#GetTitleIdInfo]] starting at the TID. However, "pad[0]" is used for something else it seems?(0 for everything except for TID [[Title_list|010000000000081B]], where it's 1)
+
Reads the meta records stored in the entry's content records into the output buffer.
   −
See [[NCA#Meta_records]].
+
This is used, for example, with System Update title 0100000000000816, which contains Meta Records for all other systitles in its Content Records.
   −
This reads the titlelist stored in the specified title, normally a title with title-type 3, which is sysupdate-title 0100000000000816. Returns 0 with total_read_entries=0 when used with other title(s).
