J. Vidal 2002-12-12 timer_create 3 timer_create create a per RTLinux process timer. #include <signal.h> int timer_create clockid_t clockid struct sigevent * restrict evp timer_t *restrict timerid This is a RTLinux version of the POSIX function timer_create() . The timer_create() function creates a per RTLinux process timer using the specified clock, clock_id, as the timing base. For further details see UNIX spec sigaction, UNIX spec timer_create In RTLinux timer_create should be called from init_module. A timer created from the RTLinux process, is available to all its threads. RTLinux Timers implementation supports both CLOCK_REALTIME and CLOCK_MONOTONIC. If the call succeeds, timer_create() shall return zero and update the location referenced by timerid to a timer_t, which can be passed to the per-process timer calls. If an error occurs, the function shall return a value of -1 and set errno to indicate the error. The value of timerid is undefined if an error occurs. The timer_create() function shall fail if: [EAGAIN]: timer_create isn't called from Linux thread (init_module). [EINVAL]: The specified clock ID is not defined.
