Here is the background info you requested. I am basically trying to call a Perl script from within a C program. However, I don't want to just make a system() call. I want to be able to capture the output (stdout) from the Perl script. If I run the Perl script on it's own, I get the output displayed to stdout. If I call it from the C program I do not. At first I thought this was a problem with my C program, but I am pretty sure it is not. Why? Because if I assign a random string (aka "Hello World") to a variable in that same Perl script and execute a print command from inside it, THEN my C program is able to capture the output from stdout. But if I use the "print $res->decode_content" command it does not. Just for clarification, here is a portion of the C program: 


char command[] = "/home/user/scripts/PerlScript.pl";
.
.
fp = popen(command, "r");
buffer = (char *)malloc(sizeof(char) * bufSize);
while( fgets(buffer, bufSize, fp) != NULL)
   fputs(buffer, stdout);
pclose(fp);
free(buffer);

The above program calls the Perl script I have written that is in question. Again, if I do the following it prints when called from the C program: 

my $randomVar = "Hello World\n";
print $randomVar;

But if I do this, it will NOT print from the C program (unless I call the Perl script by itself from the command line): 

my $res = $ua->get('http://SOMEURLHERE');
print $res->decoded_content;
