Line 93:

Returns number of entries read.

Each entry is a [[#~~ncaID~~]].

Each entry is a [[#NcaID]].

The total read entries is exactly the same as the number of "<hex>.nca" directories in the storage FS(or at least under the "registered" directory?).

== GetEntrySize ==

Takes a [[#~~ncaID~~]] as input.

Takes a [[#NcaID]] as input.

Returns the total size readable by ReadEntryRaw. This is the same as the size field from offset 0x28 in the NAX0 header in the "<~~ncaID~~>.nca/00" file. This matches <filesize of that file>-0x4000.

Returns the total size readable by ReadEntryRaw. This is the same as the size field from offset 0x28 in the NAX0 header in the "<NcaID>.nca/00" file. This matches <filesize of that file>-0x4000.

== ReadEntryRaw ==

Takes an output buffer, a [[#~~ncaID~~]] as input, and a u64 file offset.

Takes an output buffer, a [[#NcaID]] as input, and a u64 file offset.

Returns encrypted looking data. Doesn't match the encrypted raw data in the "<~~ncaID~~>.nca/00" file.

Returns encrypted looking data. Doesn't match the encrypted raw data in the "<NcaID>.nca/00" file.

See GetEntrySize for the total size readable with this.

== GetNcaTitleInfo ==

Takes a [[#~~ncaID~~]] and returns the following 0x10-sized entry. With some ~~ncaIDs~~ this may return 0 with an all-zero output entry.

Takes a [[#NcaID]] and returns the following 0x10-sized entry. With some NcaIDs this may return 0 with an all-zero output entry.

This is a 0x10-byte entry. This is originally from the hex portion of "<hex>.nca" directory-names from this storage FS(like [[SD_Filesystem|SD]]).
