hi folks,

iam a newbie to linux environment iam using popen() to run script(s) in thread(s)

all i need is my scripts should execute in parallel without starving for cpu and log the results(of scripts) in to log.

here i cannt use pclose because it will close process as well as pipe opened by popen (), i need to use this pipe for logging later.

so i did following code change in my code to acheive popen(),pclose() functionality.

is there any pitfaults/leaks with my code if so please let me know.

int main ()
{
FILE *Fp = NULL;
char buf[128]={0};
int pid;
int status;

Fp = popen("./myscript.sh", "r");
fgets(buf,128,Fp);

pid=atoi(buf);

if ( waitpid((pid_t)pid,&status,0) <0)
{
printf("wait failed:\n");
}

fclose(Fp);

return 0;
}

it is working fine but i need to know above code effects in complete process(i mean run time errors).

thx in adv
