Simple C question... Hopefully it's simple
Hello. I'm a complete newbie to C programming. I have a C program that wasn't written by me where I need to write some wrappers around it to automate and make it easier for a client to use. The problem is that the program accepts standard input to control the program... I'm hoping to find a simple way to modify the program to also accept input from a text file instead. Can someone please help me with this? I know my post is very vague, but hopefully someone can help guide me. Thanks.

lpc

lpc(8)								    Apple Inc.								    lpc(8)

NAME

       lpc - line printer control program

SYNOPSIS

       lpc [ command [ parameter(s) ] ]

DESCRIPTION

       lpc provides limited control over printer and class queues provided by CUPS. It can also be used to query the state of queues.

       If no command is specified on the command-line, lpc will display a prompt and accept commands from the standard input.

COMMANDS

       The lpc program accepts a subset of commands accepted by the Berkeley lpc program of the same name:

       exit
	    Exits the command interpreter.

       help [command]

       ? [command]
	    Displays a short help message.

       quit
	    Exits the command interpreter.

       status [queue]
	    Displays the status of one or more printer or class queues.

LIMITATIONS

       Since  lpc  is  geared  towards	the Berkeley printing system, it is impossible to use lpc to configure printer or class queues provided by
       CUPS.  To configure printer or class queues you must use the lpadmin(8) command or another CUPS-compatible client with that functionality.

COMPATIBILITY

       The CUPS version of lpc does not implement all of the standard Berkeley or LPRng commands.
