Beispiel für die Anwendung von posix_spawn()

myspawn.c

// test von posix_spawn /rb
#include <stdio.h>
#include <unistd.h>
 
int mySpawn(char *,char *,char *); 
//----------------------------------------------------
int main(int argc, char *argv[])
{
    int ret = 0;
    char *prog = "/usr/bin/avscan";
    char *arg = "--batch";
    char *buf = "/install/avira/eicar.com";
    //char *buf = "/etc/fstab";
    ret =  mySpawn(prog,arg,buf);
    printf("exitstatus von avscan: %d\n",ret);
return 0;
}
//----------------------------------------------------
int mySpawn(char *prog,char *arg,char *scanfile) 
{
 
    char* buf1[]={prog,arg,scanfile,NULL};
    int ret;
    int status = -1;
    pid_t pid;    
    ret = posix_spawn(&pid,buf1[0],NULL,NULL,buf1,NULL);
 
    if(ret == 0)
      { 
	wait(&status);
      }
    else
     {
	perror("posix_spawn");
     }
 
return status ;
}
