This was our only use of the function that had a hardcoded file descriptor.

unistd.h contains #define STDOUT_FILENO 1 Isn't that portable? see man 3p stdout
I will counter with `man 3 stdout`, namely the last bit. :) On program startup, the integer file descriptors associated with the streams stdin, stdout, and stderr are 0, 1, and 2, respectively. The preprocessor symbols STDIN_FILENO, STDOUT_FILENO, and STDERR_FILENO are defined with these values in <unistd.h>. (Applying freopen(3) to one of these streams can change the file descriptor number associated with the stream.) -Dan
