Executing a child process in "C"
Anyone know how I can run this as a separate process from the parent program, like a child process,
and return the result back to the parent program.
this script is as follows.
if file "/Stuff/s" exists then continue to run, if file "/Stuff/t" exists, then print "started" if file "/Stuff/t" does not exists, then print "stopped"
if file :thumb:"/Stuff/s" does not exist then print "quit" and then quit.
Code:
void controlxmmscheck( ) {
if( access( "/Stuff/s", F_OK ) != -1 ) {
xmmscheck
} else {
gtk_label_set_text(GTK_LABEL (label_status), gettext("quit"));
}
void controldiversion( ) {
if( access( "/Stuff/s", F_OK ) != -1 ) {
diversion
} else {
gtk_label_set_text(GTK_LABEL (label_status), gettext("quit"));
}
void xmmscheck( ) {
/* Check if /stream1/t exists */
if( access( "/Stuff/t", F_OK ) != -1 ) {
/* Then status is "started" */
gtk_label_set_text(GTK_LABEL (label_status), gettext("started"));
/* Switch to diversion function */
controldiversion
/* Or else wait for 5 seconds */
} else {
sleep(5);
/* Start this File all over again */
controlxmmscheck
}
void diversion( ) {
/* check if file /stream1/t exists */
if( access( "/Stuff/t", F_OK ) != -1 ) {
*/ Then wait for 5 Seconds */
sleep(5);
/* Start this function again */
controldiversion
} else {
/* then status is stopped */
gtk_label_set_text(GTK_LABEL (label_status), gettext("stopped"));
/* Switch to xmmscheck function */
controlxmmscheck
}
Re: Executing a child process in "C"
I have made the same script in bash,
If iwas to execute this script as a child process I would do something like
I wish to achieve a similar this in "C"
I know this may be simple for the experts, I have self taught myself by looking a source codes and figuring stuff out.
if file "/Stuff/s" exists then continue to run, if file "/Stuff/t" exists, then "mkdir /Stuff/test" if file "/Stuff/t" does not exists, then "rmdir /Stuff/test"
if file "/Stuff/s" does not exist then print or echo "quit" and then quit.
Code:
#! /bin/bash
function controlxmmscheck {
if [ -s /Stuff/s ]; then
xmmscheck
else
echo "quit controlxmmscheck"
fi
}
function controldiversion {
if [ -s /Stuff/s ]; then
diversion
else
rm /Stuff/t
echo "quit controldiversion"
fi
}
function xmmscheck {
# xmmscheck1
# Check if /stream1/t exists
if [ -s /Stuff/t ]; then
mkdir /Stuff/test
# Switch to diversion function
controldiversion
# Or else wait for 5 seconds
else
sleep 5
# Start this File all over again
controlxmmscheck
fi
}
function diversion {
# diversion
# check if file /stream1/t exists
if [ -s /Stuff/t ]; then
# Then wait for 5 Seconds
sleep 5
# Start this function again
controldiversion
else
rmdir /Stuff/test
# Switch to xmmscheck function
controlxmmscheck
fi
}
controlxmmscheck
