I found a potential solution to my problem by using a shell command;

Code:
ssh hostname 'ps -xu username | grep -i processname'

and I even got this working in a C++ program

Code:
#include <cstdio>
#include <cstdlib>
#include <cstring>
#include <iostream>

using namespace std;

int main(int argc, char** argv)
{
    string cmd = "ssh t9wst2 'ps -xu admin | grep -i applicationbar'";
    cout << "Executing" << endl;
    int result = system(cmd.c_str());
    cout << "Done: " << result << endl;
    if (0 != result)
    {
        cout << "It is not running" << endl;
    }
    else
    {
        cout << "It is running" << endl;
    }
    return 0;
}

But alas the user running my program doesn't have permission to use ssh. Any other ideas?

zgrep

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep	options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
