-/* Return a `FILE' pointer FP for the standard input of the first
- program in the pipeline; FP is opened for writing. You must have
- passed `PEX_USE_PIPES' to the `pex_init' call that returned OBJ.
- You must close FP yourself with `fclose' to indicate that the

- The file descriptor underlying FP is marked not to be inherited by

- This call is not supported on systems which do not support pipes;
- it returns with an error. (We could implement it by writing a
- temporary file, but then you would need to write all your data and
- close FP before your first call to `pex_run' -- and that wouldn't
- work on systems that do support pipes: the pipe would fill up, and
- you would block. So there isn't any easy way to conceal the
- differences between the two types of systems.)
-
- If you call both `pex_write_input' and `pex_read_output', be
- careful to avoid deadlock. If the output pipe fills up, so that
- each program in the pipeline is waiting for the next to read more
- data, and you fill the input pipe by writing more data to FP, then
- there is no way to make progress: the only process that could read
- data from the output pipe is you, but you are blocked on the input
- pipe. */
