dwarf_get_arange(3) [freebsd man page]

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.

NAME

     dwarf_get_arange_cu_header_offset, dwarf_get_cu_die_offset -- retrieve compilation unit offsets

LIBRARY

     DWARF Access Library (libdwarf, -ldwarf)

SYNOPSIS

     #include <libdwarf.h>

     int
     dwarf_get_arange_cu_header_offset(Dwarf_Arange ar, Dwarf_Off *ret, Dwarf_Error *err);

     int
     dwarf_get_cu_die_offset(Dwarf_Arange ar, Dwarf_Off *ret, Dwarf_Error *err);

DESCRIPTION

     These functions retrieve the offsets, relative to the ``.debug_info'' DWARF section, of the debugging information entries describing the com-
     pilation unit associated with a Dwarf_Arange descriptor.

     Function dwarf_get_arange_cu_header_offset() retrieves the offset of the compilation unit header associated with argument ar, and stores it
     in the location pointed to by argument ret.

     Function dwarf_get_cu_die_offset() retrieves the offset of the debugging information entry for the compilation unit associated with argument
     ar, and stores it in the location pointed to by argument ret.

     If argument err is not NULL, these functions will use it to store error information, in case of an error.

RETURN VALUES

     On success, these functions returns DW_DLV_OK.  In case of an error, they return DW_DLV_ERROR and set the argument err.

ERRORS

     These functions may fail with:

     [DW_DLE_ARGUMENT]	Argument ar was not a valid Dwarf_Arange descriptor.

     [DW_DLE_ARGUMENT]	Argument ret was NULL.
