[SOLVED]QProcess or system()

[toho71]

Should I use some QP or System() when I want to set the system time and date from my app in linux
and for the testing I would like to log in as root but I realy dont't know how to.

Later the program is going to run with root privilige but I need to test it.

Setting datetime:

@
#include <sys/time.h>
#include <stdio.h>
#include <errno.h>

int main(int argc, char *argv[])
{
struct timeval now;
int rc;

now.tv_sec=866208142;
now.tv_usec=290944;

rc=settimeofday(&now, NULL);
if(rc==0) {
    printf("settimeofday() successful.\n");
}
else {
    printf("settimeofday() failed, "
    "errno = %d\n",errno);
    return -1;
}

return 0;

}

Setuid - running program from progam as root, maybe this helps:

thanks and on monday I'll try your code and show my code too where the sytem gives a message back that this operation isn't allowed without the root priv

Well, that is not a Qt issue.

Somebody must have set up your linux installation. Only whoever that was can provide you with the details of login as root respectively provide you with root privilege.
