DWARF_GET_ARANGE(3) BSD 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 cov-
ers 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.
