spawning the same program
We have a program (reader) that reads audio files in a real-time continuous stream from a sender program. If the reader gets weird we want the sender to be able to send one command that will stop the current reader and start a new one that will be able to continue reading in the files. The sender cannot access anything other than the reader (ie, it cannot run any commands on the server, etc). The reader runs on UNIX and is written in C++.
I've tried using system() to call a batch file that sleeps for a few second and then starts a new reader. It starts a new reader but the old one stays up. I've also tried exec(), which does replace the old reader with the new one but the new reader doesn't read the audio files; it just seems to sit out there doing nothing.
Is there a way to have a program basically kill itself and start a fresh version of itself that works?
Thank you.

svn::dump::reader
SVN::Dump::Reader(3) User Contributed Perl Documentation SVN::Dump::Reader(3)
NAME
SVN::Dump::Reader - A Subversion dump reader
SYNOPSIS
# !!! You should use SVN::Dump, not SVN::Dump::Reader !!!
use SVN::Dump::Reader;
my $reader = SVN::Dump::Reader( $fh );
my $record = $reader->read_record();
DESCRIPTION
The "SVN::Dump::Reader" class implements a reader object for Subversion dumps.
METHODS
The following methods are available:
new( $fh )
Create a new "SVN::Dump::Reader" attached to the $fh filehandle.
read_record( )
Read and return a new SVN::Dump::Record object from the dump filehandle.
read_header_block( )
Read and return a new SVN::Dump::Headers object from the dump filehandle.
read_property_block( )
Read and return a new SVN::Dump::Property object from the dump filehandle.
read_text_block( )
Read and return a new SVN::Dump::Text object from the dump filehandle.
The "read_..." methods will die horribly if asked to read inconsistent data from a stream.

SVN::Dump, SVN::Dump::Headers, SVN::Dump::Property, SVN::Dump::Text.
