I have created a simple download schedular with source-code give below :

---------------------record_strokes.sh-------------------

touch /home/student/packs/lynx/logfile

lynx -cmd_log /home/student/packs/lynx/logfile

---------------------play_strokes.sh---------------------
lynx -cmd_script='/home/admin/packs/lynx/logfile' www.google.com


--------------------download_links.sh---------------------
wget http://iso.linuxquestions.org/downlo...i386-disc1.iso

wget http://iso.linuxquestions.org/downlo...i386-disc2.iso

wget http://iso.linuxquestions.org/downlo...i386-disc3.iso




--------------------halt.sh---------------------
halt


--------------------main.c---------------------

#include<stdio.h>
//#include<sys/ipc.h>
//#include<sys/shm.h>
//#include<sys/types.h>
//#include<sys/sem.h>
#include<pthread.h>

void download(void)
{
system("sh download_links.sh");
}
main()
{
pthread_t id1,id2;
system("sh record_strokes.sh");
system("sh play_strokes.sh");
pthread_create(&id1,NULL,download,NULL); // Error in 3rd para.
pthread_create(&id2,NULL,download,NULL); // Error in 3rd para.
pthread_exit(NULL);
system("sh halt.sh");
return 0;
}


So, this is a simple download scheduler program code. Which creates multiple threads of the downloading process - wget (i could also have used 'curl' instead 'wget').Can you debug this code?
Can anyone guide me please?
