Error: too many arguments to function 'sigwait'
Code:
#include <pthread.h>
#include <signal.h>
...
sigset_t mask;
int err,signo;
err=sigwait(&mask,&signo);
switch(signo){
   case SIGINT:
   ...
}

when I compile above code under solaris 10,it raise following error:
error: too many arguments to function 'sigwait'

I look up signal function under solaris10
int sigwiat(sigset_t *set);

How to correct above code to run my code?

Thanks

it is not the solution, but a single question to you ...

Code:
 I look up signal function under solaris10
int sigwiat(sigset_t *set);    -----> single argument
Code:
err=sigwait(&mask,&signo);  ------> two argument

So, that is the problem ..

I know there are two arguments in sigwait(&mask,&signo),and there is single argument int sigwait(sigset_t *set) function, sigwait(&mask,&signo) can run under unix system,but can't run under solaris system. I want to know if there is a another function to realize the same function of sigwait(&mask,&signo) under solaris?

Thanks

From here:
Code:
RETURN VALUES

     Upon  successful  completion,  sigwait()  returns  a  signal
     number.   Otherwise, it returns a value of -1 and sets errno
     to indicate an error.  Upon successful completion, the POSIX
     version  of  sigwait()  returns zero and stores the received
     signal number at the location pointed to by sig.  Otherwise,
     it returns the error number.

So the version without the pointer actually returns signo( or -1 on error ).

Dont know about Solaris but from here it looks like you need to define _POSIX_PTHREAD_SEMANTICS and include the threads lib on the compile line.
