Dwarf_Error *err);
dwarf_expr_into_block
() retrieves the byte
stream representation of a location expression.
Argument expr should reference a location expression descriptor allocated using dwarf_new_expr(3).
Argument length should point to a location which will hold the size in bytes of the retrieved byte stream.
If argument err is not NULL, it will be used to store error information in case of an error.
dwarf_expr_into_block
() returns the
address of the first byte of the generated byte stream. In case of an error,
function dwarf_expr_into_block
() returns
DW_DLV_BADADDR
and sets the argument
err.
dwarf_expr_into_block
() can fail with:
