I've downloaded Xenomai-2.0.3 and have been lookingh into signal
handling. Structs sigevent & sigaction are used in the code but I can't
find where they are declared. Can anyone help ?

thanks

Maybe browsing for them (identifier or full-text search) on this site
helps you (I do not understand yet what you are precisely looking for):

http://www.rts.uni-hannover.de/xenomai/lxr

Note that hart-RT signals are not yet supported in user space. RT user
space threads can only receive Linux signals, which will switch the
threads to secondary (non-deterministic) mode.

They come from linux/signal.h in kernel-space and signal.h in user-space.

Jan,

I was looking for the definition of sigevent particularly:-

typedef struct sigevent
  {
    sigval_t sigev_value;
    int sigev_signo;
    int sigev_notify;

    union
      {
	int _pad[__SIGEV_PAD_SIZE];

	struct
	  {
	    void (*_function) (sigval_t);	/* Function to start.
*/
	    void *_attribute;			/* Really
pthread_attr_t.  */
	  } _sigev_thread;
      } _sigev_un;
  } sigevent_t;

I was looking only in the Xenomai code, from Giles email I should also
have looked in the linux source where I found it in siginfo.h. Afraid
I'm not just new to Xenomai but Linux also!

Regards
