Member Function Documentation

from_svr_data()

template<typename T>

constexpr int L4::Ipc::Msg::Svr_noops< T >::from_svr_data ( char * msg, unsigned offset, unsigned limit, T const & arg )

inlinestaticconstexprnoexcept

Write IPC data of arg into UTCB.

Called only for output arguments.

Parameters

msg	Pointer to first usable UTCB MR
offset	Byte offset into UTCB MRs
limit	Maximum number of bytes available in msg array
arg	The IPC argument

Return values

<0	Error code
>=0	Offset into msg for next IPC argument

Definition at line 309 of file ipc_basics.

from_svr_items()

template<typename T>

constexpr int L4::Ipc::Msg::Svr_noops< T >::from_svr_items ( char * msg, unsigned offset, unsigned limit, T const & arg )

inlinestaticconstexprnoexcept

Write IPC send items of arg into UTCB.

Called only for output arguments.

Parameters

msg	Pointer to first usable UTCB MR
offset	Byte offset into UTCB MRs
limit	Maximum number of bytes available in msg array
arg	The IPC argument

Return values

<0	Error code
>=0	Offset into msg for next IPC argument

Definition at line 328 of file ipc_basics.

reserve_data()

template<typename T>

constexpr int L4::Ipc::Msg::Svr_noops< T >::reserve_data ( char * msg, unsigned offset, unsigned limit, T & arg )

inlinestaticconstexprnoexcept

Reserve IPC data bytes in UTCB.

Called only for output arguments. The argument type may remember the msg pointer if the data is put directly into the UTCB.

Parameters

msg	Pointer to first usable UTCB MR
offset	Byte offset into UTCB MRs
limit	Maximum number of bytes available in msg array
arg	The IPC argument

Return values

<0	Error code
>=0	Offset into msg for next IPC argument

Definition at line 348 of file ipc_basics.

to_svr_data()

template<typename T>

constexpr int L4::Ipc::Msg::Svr_noops< T >::to_svr_data ( char * msg, unsigned offset, unsigned limit, T & arg )

inlinestaticconstexprnoexcept

Read IPC data for arg from UTCB.

Called only for input arguments.

Parameters

	msg	Pointer to first filled UTCB MR
	offset	Byte offset into UTCB MRs
	limit	Number of bytes available in msg array
[out]	arg	The IPC argument

Return values

<0	Error code
>=0	Offset into msg for next IPC argument

Definition at line 367 of file ipc_basics.

to_svr_items()

template<typename T>

constexpr int L4::Ipc::Msg::Svr_noops< T >::to_svr_items ( char * msg, unsigned offset, unsigned limit, T & arg )

inlinestaticconstexprnoexcept

Read IPC return items for arg from UTCB.

Called only for input arguments.

Parameters

	msg	Pointer to first filled UTCB MR
	offset	Byte offset into UTCB MRs
	limit	Number of bytes available in msg array
[out]	arg	The IPC argument

Return values

<0	Error code
>=0	Offset into msg for next IPC argument
