## #33832 — Nathan Rixham — 2007-12-07T15:47:11+00:00

URL: https://externals.io/message/33832#33832

proc_open() pipes:
when stdout and stderr are set to file no resource pointers are returned 
in the pipes array

when using fwrite on a pipe to stdin (from `proc_open()`)
 `fflush()` does not work,
neither does `stream_set_write_buffer()`;
regardless of whether stdout/stderr are mapped to pipes or files, infact 
in all my tests I cannot get php to return anything through stdout or 
stderr until fclose on stdin has occured, even then support for 
stream_get_meta_data seems to be distinctly lacking.

Perhaps there is a method I am missing however support for multiple 
process read/writes seems a little lacking (impossible?), and in my 
opinion should/could be expanded.

Suggestions/Thoughts?
