Function dwarf_die_CU_offset
() returns the
offset of the debugging information entry referenced by argument
die relative to the start of its containing
compilation unit. Argument ret_offset should point to
the location that is to hold the returned offset. If argument
err is non-NULL, it will be used to return an error
descriptor in case of an error.
Function dwarf_die_CU_offset_range
()
returns the section-relative offset and length of the compilation unit
containing the debugging information entry referenced by argument
die. Argument cu_offset should
point to a location that will hold the returned offset. Argument
cu_length should point to a location that will hold
the returned length of the compilation unit. If argument
err is non-NULL, it will be used to return an error
descriptor in case of an error.
Function dwarf_dieoffset
() retrieves the
section-relative offset of the debugging information entry referenced by
argument die. Argument
ret_offset should point to a location that is to hold
the returned section-relative offset. If argument err
is non-NULL, it will be used to return an error descriptor in case of an
error.
Function
dwarf_get_cu_die_offset_given_cu_header_offset
()
returns the offset for the first debugging information entry for a
compilation unit, given an offset to the header of the compilation unit.
Argument dbg should reference a valid debugging
context allocated using
dwarf_init(3). Argument
in_cu_header_offset contains the offset to the start
of a compilation unit. Argument out_cu_die_offset
points to a location that will hold the returned offset. If argument
err is non-NULL, it will be used to return an error
descriptor in case of an error.
Function
dwarf_get_cu_die_offset_given_cu_header_offset_b
()
behaves identically to the function
dwarf_get_cu_die_offset_given_cu_header_offset
()
when the argument is_info is non-zero. When the
argument is_info is zero, function
dwarf_get_cu_die_offset_given_cu_header_offset_b
()
returns the offset for the first debugging information entry for a type
unit, given an offset to the header of the type unit in argument
in_cu_header_offset. Argument
out_cu_die_offset points to a location that will hold
the returned offset. If the argument err is non-NULL,
it will be used to return an error descriptor in case of an error.
DW_DLV_OK
. In case of
an error, these functions return DW_DLV_ERROR
and set
argument err.
Function
dwarf_get_cu_die_offset_given_cu_header_offset
() and
dwarf_get_cu_die_offset_given_cu_header_offset_b
()
returns DW_DLV_NO_ENTRY
and sets argument
err if there is no compilation or type unit located at
the offset specified in argument
in_cu_header_offset.
