DWARF_GET_CIE_OF_FDE(3) 				   BSD Library Functions Manual 				   DWARF_GET_CIE_OF_FDE(3)

NAME

     dwarf_get_cie_of_fde -- retrieve CIE descriptor

LIBRARY

     DWARF Access Library (libdwarf, -ldwarf)

SYNOPSIS

     #include <libdwarf.h>

     int
     dwarf_get_cie_of_fde(Dwarf_Fde fde, Dwarf_Cie *ret_cie, Dwarf_Error *err);

DESCRIPTION

     Function dwarf_get_cie_of_fde() retrieves the CIE descriptor associated with a given FDE descriptor.

     Argument fde should reference a valid FDE descriptor.

     Argument ret_cie should point to a location that will hold the returned CIE 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_cie_of_fde() returns DW_DLV_OK when it succeeds.  In case of an error, it returns DW_DLV_ERROR and sets the argument err.

ERRORS

     Function dwarf_get_cie_of_fde() can fail with:

     [DW_DLE_ARGUMENT]	Either of arugments fde or ret_cie was NULL.

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
     specified 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 specified by argument pc.
