Description
This copies the metadata for all slots that need to be sent into the specified buffer.
Each metadata object consists out of a tuple of three words: send method, title_id, size whereas the size is the size in bytes of the corresponding spr slot. Copies up to buffer size / (4*3) slots into the buffer.
Returns the amount of slots read, not the amount of bytes read.
Requires the Cec Spr Status to be CEC_SPR_SEND_RECV_INIT.
