20 pt_insn_get_offset() provides decoder's current position as offset in
21 bytes from the beginning of decoder's trace buffer in the unsigned in‐
22 teger variable pointed to by offset.
23
24 pt_insn_get_sync_offset() provides decoder's last synchronization point
25 as offset in bytes from the beginning of decoder's trace buffer in the
26 unsigned integer variable pointed to by offset.
27
29 Both functions return zero on success or a negative pt_error_code enu‐
30 meration constant in case of an error.
31
33 pte_invalid
34 The decoder or offset argument is NULL.
35
36 pte_nosync
37 decoder has not been synchronized onto the trace stream. Use
38 pt_insn_sync_forward(3), pt_insn_sync_backward(3), or pt_in‐
39 sn_sync_set(3) to synchronize decoder.
