I know that I can use us the foundation framework to run a command line utility. The problem is that about half of the output from one of the utilities I need to run is lost. It just never reaches the main application. However in another program I use the security framework to run a command line utility and I use a FILE pointer to retrieve the data from stdout and it works perfectly. So I am wondering is there a way to run a command line utility where I use a FILE pointer to retrieve the output that is similar to the security framework without actually using that framework? I looked at the primitive system() command but that does not accept a FILE pointer.
Thanks for any help.

NSTask works if that is what you mean by "[using] foundation framework".

So either you are using NSTask incorrectly or the command you are running is outputing some of its output to stderr.

Can you outline how you are using NSTask? If I had to guess (which I do) I bet you wait on the process to terminate and continue on once it does without correctly looping until you have no more data to read from the NSPipe related to the task.
