Content filtering is enabled when this word isn't 0xffffffff. This is only used for the following: <code>if(filterword_u16high!=contententryword_u16high || (filterword_u16low & contententryword_u16low) == 0)continue;</code> The contententryword is separate from NsDataId. The NsDataId for the content entry is only written to the output when these checks pass.

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.
