DWARF_GET_ARANGE(3)        Library Functions Manual        DWARF_GET_ARANGE(3)

NAME
     dwarf_get_arange - retrieve the address range descriptor for an address

LIBRARY
     DWARF Access Library (libdwarf, -ldwarf)

SYNOPSIS
     #include <libdwarf.h>

     int
     dwarf_get_arange(Dwarf_Arange *ar_list, Dwarf_Unsigned ar_cnt,
         Dwarf_Addr addr, Dwarf_Arange *ret_ar, Dwarf_Error *err);

DESCRIPTION
     Function dwarf_get_arange() searches an array of Dwarf_Arange descriptors
     for one that covers a given address.

     Argument ar_list should point to an array of Dwarf_Arange descriptors.

     Argument ar_cnt specifies the number of Dwarf_Arange descriptors in the
     array pointed to by argument ar_list.

     Argument addr specifies the address being looked up.

     Argument ret_ar will be used to store the Dwarf_Arange descriptor that
     covers the given address.

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

RETURN VALUES
     Function dwarf_get_arange() returns DW_DLV_OK when it succeeds.  It
     returns DW_DLV_NO_ENTRY if there is no Dwarf_Arange descriptor that
     covers the provided address.  In case of an error, it returns
     DW_DLV_ERROR and sets the argument err.

ERRORS
     Function dwarf_get_arange() can fail with:

     [DW_DLE_ARGUMENT]       One of the arguments dbg, ar_list or ret_ar was
                             NULL.

     [DW_DLE_ARGUMENT]       Value of argument ar_cnt equals to 0.

     [DW_DLE_NO_ENTRY]       A Dwarf_Arange descriptor that covers the given
                             address was not found.
