A reference to an abstract timer.
UserTimer(io_ctx_t *ctx, ev_exec_t *exec, io_user_timer_setnext_t *func=nullptr, void *arg=nullptr)
const struct ev_exec_vtbl *const ev_exec_t
An abstract task executor.
This header file is part of the I/O library; it contains the user-defined timer declarations.
io_timer_t * io_user_timer_create(io_ctx_t *ctx, ev_exec_t *exec, io_user_timer_setnext_t *func, void *arg)
Creates a new user-defined timer.
void io_user_timer_destroy(io_timer_t *timer)
Destroys a user-defined timer.
void io_user_timer_setnext_t(const struct timespec *tp, void *arg)
