API an external event loop has to implement for #GNUNET_SCHEDULER_driver_init.

Fields

cls: *mut c_void

Closure to pass to the functions in this struct.

add: Option<unsafe extern "C" fn(cls: *mut c_void, task: *mut GNUNET_SCHEDULER_Task, fdi: *mut GNUNET_SCHEDULER_FdInfo) -> c_int>

Add a @a task to be run if the conditions specified in the et field of the given @a fdi are satisfied. The et field will be cleared after this call and the driver is expected to set the type of the actual event before passing @a fdi to #GNUNET_SCHEDULER_task_ready.

@param cls closure @param task task to add @param fdi conditions to watch for @return #GNUNET_OK on success, #GNUNET_SYSERR on failure (i.e. @a fdi too high or invalid)

del: Option<unsafe extern "C" fn(cls: *mut c_void, task: *mut GNUNET_SCHEDULER_Task) -> c_int>

Delete a @a task from the set of tasks to be run. A task may comprise multiple FdInfo entries previously added with the add function. The driver is expected to delete them all.

@param cls closure @param task task to delete @return #GNUNET_OK on success, #GNUNET_SYSERR on failure (i.e. @a task does not match prior @e add call)

set_wakeup: Option<unsafe extern "C" fn(cls: *mut c_void, dt: GNUNET_TIME_Absolute)>

Set time at which we definitively want to get a wakeup call.

@param cls closure @param dt time when we want to wake up next
