dwarf_get_arange -- retrieve the address range descriptor for an address
DWARF Access Library (libdwarf, -ldwarf)
#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);
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.
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.
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.
