Dwarf_Unsigned *ret_len, Dwarf_Error
*error);
dwarf_get_fde_instr_bytes
() retrieves
instruction bytes from a given FDE descriptor.
Argument fde should reference a valid DWARF FDE descriptor.
Argument ret_inst should point to a location that will be set to a pointer to an array of bytes containing the instructions of the FDE descriptor.
Argument ret_len should point to a location that will hold the length in bytes of the instructions returned in argument ret_inst.
If argument err is not NULL, it will be used to store error information in case of an error.
Applications can use the function dwarf_expand_frame_instructions(3) to parse and expand the returned instruction bytes into an array of Dwarf_Frame_Op descriptors.
dwarf_get_fde_instr_bytes
() returns
DW_DLV_OK
when it succeeds. In case of an error, it
returns DW_DLV_ERROR
and sets the argument
err.
dwarf_get_fde_instr_bytes
() can fail with:
DW_DLE_ARGUMENT
