You could just send some sort of message wrapper
to the FIFO that your program can read.
Effectively setting up an application level
protocol... SYN SYN SOH... sqlplus data ...EOD

Also, you could write the shell script to launch
your C program in the background and grab the
PID of that program (i.e. PROGPID=$!). You
can the send a signal (see kill(1) man page) to
your program to tell it all is OK or not. Your
code would of course have to properly handle the
signals you choose to send (see signal(5) man
page).

NAME
raise - send a signal to the caller SYNOPSIS
#include <signal.h> int raise(int sig); DESCRIPTION
The raise() function sends a signal to the calling process or thread. In a single-threaded program it is equivalent to kill(getpid(), sig); In a multithreaded program it is equivalent to pthread_kill(pthread_self(), sig); If the signal causes a handler to be called, raise() will only return after the signal handler has returned. RETURN VALUE
raise() returns 0 on success, and nonzero for failure. CONFORMING TO
C89, C99, POSIX.1-2001. SEE ALSO
