+.Sh DESCRIPTION
+Function
+.Fn dwarf_get_arange
+searches an array of
+.Vt Dwarf_Arange
+descriptors for one that covers a given address.
+.Pp
+Argument
+.Ar ar_list
+should point to an array of
+.Vt Dwarf_Arange
+descriptors.
+.Pp
+Argument
+.Ar ar_cnt
+specifies the number of
+.Vt Dwarf_Arange
+descriptors in the array pointed to by argument
+.Ar ar_list .
+.Pp
+Argument
+.Ar addr
+specifies the address being looked up.
+.Pp
+Argument
+.Ar ret_ar
+will be used to store the
+.Vt Dwarf_Arange
+descriptor that covers the given address.
+.Pp
+If argument
+.Ar err
+is not NULL, it will be used to store error information in case of an
+error.
+.Sh RETURN VALUES
+Function
+.Fn dwarf_get_arange
+returns
+.Dv DW_DLV_OK
+when it succeeds.
+It returns
+.Dv DW_DLV_NO_ENTRY
+if there is no
+.Vt Dwarf_Arange
+descriptor that covers the provided address.
+In case of an error, it returns
+.Dv DW_DLV_ERROR
+and sets the argument
+.Ar err .
+.Sh ERRORS
+Function
+.Fn dwarf_get_arange
+can fail with:
+.Bl -tag -width ".Bq Er DW_DLE_NO_ENTRY"
+.It Bq Er DW_DLE_ARGUMENT
+One of the arguments
+.Ar dbg ,
+.Ar ar_list
+or
+.Ar ret_ar
+was NULL.
+.It Bq Er DW_DLE_ARGUMENT
+Value of argument
+.Ar ar_cnt
+equals to 0.
+.It Bq Er DW_DLE_NO_ENTRY
+A
+.Vt Dwarf_Arange
+descriptor that covers the given address
+was not found.
