Hello,
imm trying to create a small window that shows me if a serice is running and
displays a small icon that shows the status
i created this function that checks if a PID is there:
gint check_samba(){
gint smb_pid2;
gchar check_smb_cmd[512];
sprintf(check_smb_cmd, "cat /var/run/samba/smbd.pid 2>/dev/null");
//g_print("%s", check_smb_cmd);
smb_pid2 = system(check_smb_cmd);
//g_print("%s", smb_pid2);
return smb_pid2;
}
the function is called here:
gint smb_pid;
smb_pid=check_samba();
//g_print("PID: %i", smb_pid);
//while(1){
if(smb_pid > 0)
{
image1 = g_object_new(GTK_TYPE_IMAGE,"file", "pics/ledgreen.png",
NULL);
}else{
image1 = g_object_new(GTK_TYPE_IMAGE,"file", "pics/ledred.png",
NULL);
}
//}
gtk_widget_show (image1);
So how can I check and if neccessary change the picture lets say every each
2 seconds?
I thought i could use an endless while loop, but that didnt worked.
Also the PID gets displayes when I call the function, but a g_print("PID:
%i", smb_pid); give me (null)
has been quite a while since i worked with C, so this may be a dump error by
me.
thx for your help
