# NAME
pt_insn_get_offset, pt_insn_get_sync_offset - get an Intel(R) Processor Trace
instruction flow decoder's current/synchronization trace buffer offset
# SYNOPSIS
| **\#include `<intel-pt.h>`**
|
| **int pt_insn_get_offset(const struct pt_insn_decoder \**decoder*,**
| **uint64_t \**offset*);**
| **int pt_insn_get_sync_offset(const struct pt_insn_decoder \**decoder*,**
| **uint64_t \**offset*);**
Link with *-lipt*.
# DESCRIPTION
**pt_insn_get_offset**() provides *decoder*'s current position as offset in
bytes from the beginning of *decoder*'s trace buffer in the unsigned integer
variable pointed to by *offset*.
**pt_insn_get_sync_offset**() provides *decoder*'s last synchronization point as
offset in bytes from the beginning of *decoder*'s trace buffer in the unsigned
integer variable pointed to by *offset*.
# RETURN VALUE
Both functions return zero on success or a negative *pt_error_code* enumeration
constant in case of an error.
# ERRORS
pte_invalid
: The *decoder* or *offset* argument is NULL.
pte_nosync
: *decoder* has not been synchronized onto the trace stream. Use
**pt_insn_sync_forward**(3), **pt_insn_sync_backward**(3), or
**pt_insn_sync_set**(3) to synchronize *decoder*.
