# NAME

pt_enc_get_offset, pt_enc_sync_set - get/set an Intel(R) Processor Trace packet

encoder's current trace buffer offset

# SYNOPSIS

| **\#include `<intel-pt.h>`**

|

| **int pt_enc_get_offset(struct pt_packet_encoder \**encoder*,**

|                       **uint64_t \**offset*);**

| **int pt_enc_sync_set(struct pt_packet_encoder \**encoder*,**

|                     **uint64_t *offset*);**

Link with *-lipt*.

# DESCRIPTION

**pt_enc_get_offset**() provides *encoder*'s current position as offset in bytes

from the beginning of *encoder*'s trace buffer in the unsigned integer variable

pointed to by *offset*.

**pt_enc_sync_set**() sets *encoder*'s current position to *offset* bytes from

the beginning of its trace buffer.

# 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 *encoder* or *offset* (for **pt_enc_sync_set**()) argument is NULL.

pte_eos

:   The *offset* argument is too big and the resulting position would be outside

    of *encoder*'s trace buffer (**pt_enc_sync_set**() only).
