if i have a funtion (eg: parse_file(FILE *f)) and i want to read the 
output (eg: stdout) of another program that is ran via one of the spawn() 
functions, how could i redirect the spawned process's stdout to be a file 
stream for the parse_file() function?

in other words, i would like to do something much cleaner than the 
following:

system("program.exe -args  > datafile.tmp");
f=fopen("datafile.tmp","rt");
if (!f) do_error();
parse_file(f);
close(f);


thanks much in advance!!
