    Use of 'static' keyword

    In the following code, would static be used just to keep the function sig_usr() file scoped? Or this there more to using static in this example.

    Code:
    #include <signal.h>
    #include <stdio.h>
    #include <unistd.h>
    
    static void sig_usr(int signo) {
        if(signo == SIGUSR1)
            printf("received SIGUSR1\n");
    
    }
    
    int main(void) {
        if (signal(SIGUSR1,sig_usr) == SIG_ERR)
            fprintf(stderr,"can't catch signal");
        for(;;)
            pause();
    }

    That's all there is to it.
