DWARF_GET_FDE_AT_PC(3)	 BSD Library Functions Manual	DWARF_GET_FDE_AT_PC(3)

NAME
     dwarf_get_fde_at_pc -- retrieve the FDE descriptor	for an address

LIBRARY
     DWARF Access Library (libdwarf, -ldwarf)

SYNOPSIS
     #include <libdwarf.h>

     int
     dwarf_get_fde_at_pc(Dwarf_Fde *fdelist, Dwarf_Addr	pc,
	 Dwarf_Fde *ret_fde, Dwarf_Addr	*lopc, Dwarf_Addr *hipc,
	 Dwarf_Error *err);

DESCRIPTION
     Function dwarf_get_fde_at_pc() searches the provided array	of DWARF FDE
     descriptors for a descriptor covering a given program counter address.

     Argument fdelist should point to an array of FDE descriptors, as returned
     by	the functions dwarf_get_fde_list(3) or dwarf_get_fde_list_eh(3).

     Argument pc should	contain	the program counter address being looked up.

     Argument ret_fde should point to a	location that will hold	the returned
     FDE descriptor.

     Argument lopc should point	to a location that will	be set to the lowest
     address covered by	the returned FDE descriptor.

     Argument hipc should point	to a location that will	be set to the highest
     address covered by	the returned FDE descriptor.

     If	argument err is	not NULL, it will be used to store error information
     in	case of	an error.

RETURN VALUES
     Function dwarf_get_fde_at_pc() returns DW_DLV_OK when it succeeds.	 It
     returns DW_DLV_NO_ENTRY if	a FDE descriptor that covers the address spec-
     ified by argument pc is not found.	 In case of an error, it returns
     DW_DLV_ERROR and sets the argument	err.

ERRORS
     Function dwarf_get_fde_at_pc() can	fail with:

     [DW_DLE_ARGUMENT]	One of the arguments fdelist, ret_fde, lopc, or	hipc
			was NULL.

     [DW_DLE_NO_ENTRY]	These was no FDE descriptor covering the address spec-
			ified by argument pc.
