@args=("$pipeline/EXE/searchXY", "-5", "UEB2K005I", "$TRI", "234", "156", "4", "Print");
system(@args);

I have the above C program with its arguments in the standard way. It is not really important what the program does, as I need to do this for several different programs.

The program expects a filename in place of $TRI, or a variable with a string in it which will be used as the filename. The output is then printed to a textfile with the filename.

I want to instead send the output to a pipe so I can read it without going through writing to and accessing a text file, so I speed up the processing as this gets repeated many thousands of times.

I can not append the program call with a pipe, because the results do not go there. I need to trick the C program into thinking a pipe handle is a textfile.

How do I do this? Perhaps I need to invoke the program in a different way? Is it even possible?

Considered by Tanktalus - code tags, please
