NAME

       uwx_step() - step one frame

SYNOPSIS


DESCRIPTION

       is  part  of  the Unwind Express Library for Integrity systems; see uwx(3X).  steps back one frame from the current context and updates the
       context to reflect the state of the new frame.  The return pointer becomes the new IP (instruction pointer),  the  previous  stack  pointer
       becomes	the  new stack pointer, the backing store pointer is adjusted to point to the previous frame's registers, the previous frame state
       becomes the new current frame marker, and all preserved registers are updated with the values they had in that frame.  (If has been used to
       disable floating-point register tracking, the preserved floating-point registers will not be updated.)

   Parameters
       env	      A pointer to an unwind environment object.

RETURN VALUE

       returns on success.  If the current frame is at the bottom of the call stack, it returns and the current context is unchanged.  If the cur-
       rent frame is a signal frame (or some other ABI-dependent context frame), it returns and the current context is unchanged.  All other  sta-
       tus codes indicate errors; see uwx(3X) for error codes.

NAME

       uwx_get_sym_info() - return symbolic information for current frame

SYNOPSIS


DESCRIPTION

       is part of the Unwind Express Library for Integrity systems; see uwx(3X).  obtains symbolic information for the current frame from the sym-
       bol tables in the ELF object file, if available.

       This entry point is provided for use immediately following a call to For other situations, see

   Parameters
       env	      A pointer to an unwind environment object.

       modp	      Pointer to a variable of type char * where the load module name will be returned.  If NULL, the  module  name  will  not	be
		      returned.  If the module name is not available, a NULL pointer will be returned.

       funcp	      Pointer  to  a  variable	of  type  char * where the function name will be returned.  If NULL, the function name will not be
		      returned.  If the function name is not available, a NULL pointer will be returned.

       offsetp	      Pointer to a variable of type uint64_t where the function offset (the difference between the IP  (instruction  pointer)  and
		      the  actual value of the function symbol located) will be returned.  If NULL, the offset will not be returned.  If the func-
		      tion name is not available, an offset of 0 will be returned.

RETURN VALUE

       returns on success.  If the current frame is a signal handler frame, it returns and no symbolic information is returned.  See  uwx(3X)  for
       error codes.
