Request
| Index Word | Description |
|---|---|
| 0 | Header code [0x00100102] |
| 1 | u32 filter |
| 2 | Buffer size in words(max entries). |
| 3 | u16, starting word-index in the internal NsDataId list. Added with 0x1 to determine the actual word-index. 0xFFFF is for using actual-word-index 0. |
| 4 | u32, unknown. |
| 5 | Descriptor for mapping a write-only buffer in the target process |
| 6 | Destination pointer |
Response
| Index Word | Description |
|---|---|
| 0 | Header code |
| 1 | Result code |
| 2 | u16 Actual number of output entries. |
| 3 | u16 Last word-index copied to output in the internal NsDataId list. |
Filter
Content filtering is enabled when this word isn't 0xffffffff. This is only used for the following: if(filterword_u16high!=contententryword_u16high || (filterword_u16low & contententryword_u16low) == 0)continue; The contententryword is separate from NsDataId. The NsDataId for the content entry is only written to the output when these checks pass.
Description
This writes an array of u32 entries(NsDataId) to the output buffer, for the current programID.
This eventually calls a function with the following type parameters: 0, 1, 1. This function doesn't use the second type parameter. Afterwards another function is called using the programID.
