dwarf_get_fde_at_pc
() searches the provided
array of DWARF FDE descriptors for a descriptor covering a given program
counter address.
Argument fdelist should point to an array of FDE descriptors, as returned by the functions dwarf_get_fde_list(3) or dwarf_get_fde_list_eh(3).
Argument pc should contain the program counter address being looked up.
Argument ret_fde should point to a location that will hold the returned FDE descriptor.
Argument lopc should point to a location that will be set to the lowest address covered by the returned FDE descriptor.
Argument hipc should point to a location that will be set to the highest address covered by the returned FDE descriptor.
If argument err is not
NULL
, it will be used to store error information in
case of an error.
dwarf_get_fde_at_pc
() returns
DW_DLV_OK
when it succeeds. It returns
DW_DLV_NO_ENTRY
if a FDE descriptor that covers the
address specified by argument pc is not found. In case
of an error, it returns DW_DLV_ERROR
and sets the
argument err.
dwarf_get_fde_at_pc
() can fail with:
