# NAME
pt_insn_get_image, pt_insn_set_image - get/set an Intel(R) Processor Trace
instruction flow decoder's traced memory image descriptor
# SYNOPSIS
| **\#include `<intel-pt.h>`**
|
| **struct pt_image \*pt_insn_get_image(struct pt_insn_decoder \**decoder*);**
|
| **int pt_insn_set_image(struct pt_insn_decoder \**decoder*,**
| **struct pt_image \**image*);**
Link with *-lipt*.
# DESCRIPTION
**pt_insn_get_image**() returns the traced memory image descriptor that
*decoder* uses for reading instruction memory. See **pt_image_alloc**(3).
Every decoder comes with a default *pt_image* object that is initially empty and
that will automatically be destroyed when the decoder is freed.
**pt_insn_set_image**() sets the traced memory image descriptor that *decoder*
uses for reading instruction memory. If the *image* argument is NULL, sets
*decoder*'s image to be its default image. The user is responsible for freeing
the *pt_image* object that *image* points to when it is no longer needed.
# RETURN VALUE
**pt_insn_get_image**() returns a pointer to *decoder*'s *pt_image* object. The
returned pointer is NULL if the *decoder* argument is NULL.
**pt_insn_set_image**() returns zero on success or a negative *pt_error_code*
enumeration constant in case of an error.
# ERRORS
pte_invalid
: The *decoder* argument is NULL.
# NOTES
One *pt_image* object must not be shared between multiple decoders. Use
**pt_image_copy**(3) to copy a common image.
