Where is your gets()? Also when you do a fputs(), you need to call
fflush(). But in general, your gets() should help you with that.

Hi guys,

Sorry for the late reply.

@Luke: Yeap, my fputs is showing up. I have already solved the problem of execve-ing to my program. However, another problem has popped up. If user input is not received, my intention is for the rest of the init process to continue as normal so the phone can boot up. However I'm getting stuff like 

this: http://pastebin.com/XxCZeECs. I've tried to integrate my custom program code into init.c only to run into the same problem!  Can anyone explain what's going on?

@Naresh: My apologies. The if (user input received) is in psuedocode. My fgets() stuff is all there, I just didn't type it out.

I think you can include the execution of your test tool in the init script instead of modifying init.c

But I need to run my test tool before Android boots up. I did explore running via the init.rc script, but I didn't know how to have the test tool take control of the console.

However, I managed to solve my problem as described in this link:

Thanks guys!
