pkill: implement --queue

[Bluemangoo]

wrote a tool to test:

$ ./sigr                    
I'm 99648
recv a sig = 2 data = 10 data = 10

$ cargo run -q pkill -SIGINT -q 10 sigr -e
./sigr killed (pid 99648)

could you please add a test ?

Common distributions do not have commands to detect output queues. The tool mentioned above is written in C++.

It might be difficult to test if it really working only with rust tests. btw, test_pkill.rs only contains tests for invalid arguments. I think we can open an issue for this.

#include <string.h>
#include <signal.h>
#include <unistd.h>
#include <stdlib.h>
#include <stdio.h>
 
void handler(int, siginfo_t *, void*);
 
int main(int argc, char *argv[])
{
    printf("I'm %d\n", getpid());
    struct sigaction act;
    act.sa_sigaction = handler;
    sigemptyset(&act.sa_mask);
    act.sa_flags = SA_SIGINFO;
    
    if(sigaction(SIGINT, &act, NULL) < 0) {
        perror("sigaction error");
        exit(0);
    }
    for(; ;)
      pause();
    return 0;
}
 
void handler(int sig, siginfo_t *info, void *ctx)
{
    printf("recv a sig = %d data = %d data = %d\n", sig, info->si_value.sival_int, info->si_int);
}

added a simple test for invalid input.
