try this
/* connect stdin & stdout to the files you want to process */
freopen("c:/directory/filename.ext", "r", stdin);
freopen("c:/directory/filename.ext", "w", stdout);
/* spawn the program */
spawnlp(P_WAIT, "sort", "sort", NULL);
/* connect stdin & stdout back to the console */
freopen("con", "r", stdin);
freopen("con", "w", stdout);
