NAME

       uwx_self_do_context_frame() - reinitialize the context at a signal frame

SYNOPSIS


DESCRIPTION

       is  part  of  the  Unwind Express Library for Integrity systems; see uwx(3X).  builds a new context in the unwind environment from a signal
       frame.  This entry point should be called after (and only after) returns the status code and returns an abi code of 1 and a context code of
       1, indicating that an HP-UX signal frame has been reached.

       Upon return, the current context in the unwind environment will reflect the state of the process at the point where the signal occurred.

       This entry point is to be used only when self-unwinding, using the provided callback routines.

   Parameters
       env	      A pointer to an unwind environment object.

       info	      A pointer to the self-unwind callback info structure.

RETURN VALUE

       returns on success.  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.
