+.Sh LIBRARY
+.Lb libdwarf
+.Sh SYNOPSIS
+.In libdwarf.h
+.Ft int

+.Sh DESCRIPTION
+Function
+.Fn dwarf_get_fde_instr_bytes
+retrieves instruction bytes from a given FDE descriptor.
+.Pp
+Argument
+.Ar fde
+should reference a valid DWARF FDE descriptor.
+.Pp
+Argument
+.Ar 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.
+.Pp
+Argument
+.Ar ret_len
+should point to a location that will hold the length in
+bytes of the instructions returned in argument
+.Ar ret_inst .
+.Pp
+If argument
+.Ar err
+is not NULL, it will be used to store error information in case of an
+error.
+.Pp
+Applications can use the function
+.Xr dwarf_expand_frame_instructions 3
+to parse and expand the returned instruction bytes into an array of
+.Vt Dwarf_Frame_Op
+descriptors.
+.Sh RETURN VALUES
+Function
+.Fn dwarf_get_fde_instr_bytes
+returns
+.Dv DW_DLV_OK
+when it succeeds.
+In case of an error, it returns
+.Dv DW_DLV_ERROR
+and sets the argument
+.Ar err .
+.Sh ERRORS
+Function
+.Fn dwarf_get_fde_instr_bytes
+can fail with:
+.Bl -tag -width ".Bq Er DW_DLE_ARGUMENT"
+.It Bq Er DW_DLE_ARGUMENT
+One of the arguments
+.Ar fde ,
+.Ar ret_inst
+or
+.Ar ret_len
+was NULL.
