Detailed Description

template<typename LOOP_HOOKS = Ipc_svr::Default_loop_hooks>
class L4::Server< LOOP_HOOKS >

Basic server loop for handling client requests.

LOOP_HOOKSthe server inherits from LOOP_HOOKS and calls the hooks defined in LOOP_HOOKS in the server loop. See Ipc_svr::Default_loop_hooks, Ipc_svr::Ignore_errors, Ipc_svr::Default_timeout, Ipc_svr::Compound_reply, and Ipc_svr::Br_manager_no_buffers.

This is basically a simple server loop that uses a single message buffer for receiving requests and sending replies. The dispatcher determines how incoming messages are handled.

Constructor & Destructor Documentation

◆ Server()

template<typename LOOP_HOOKS = Ipc_svr::Default_loop_hooks>
L4::Server< LOOP_HOOKS >::Server ( l4_utcb_t utcb)

Initializes the server loop.

utcbThe UTCB of the thread running the server loop.

Member Function Documentation

◆ internal_loop()

template<typename L >
template<typename DISPATCH >
L4_NORETURN void L4::Server< L >::internal_loop ( DISPATCH  dispatch)

The server loop.

This function usually never returns, it waits for incoming messages calls the dispatcher, sends a reply and waits again.

Definition at line 360 of file ipc_server_loop.

◆ loop()

template<typename LOOP_HOOKS = Ipc_svr::Default_loop_hooks>
template<typename EXC , typename R >
L4_NORETURN void L4::Server< LOOP_HOOKS >::loop ( r)

Server loop with internal exception handling.

This server loop translates L4::Runtime_error exceptions into negative error return codes sent to the caller.
