[PATCH v3 0/6] Force pipes to flush immediately on NonStop platform

randall.s.becker@rogers.com· Jan 19, 2018, 23:00 UTC · lore

From: "Randall S. Becker" <rsbecker@nexbridge.com>

* wrapper.c: called setbuf(stream,NULL) to force pipe flushes not
  enabled by default on the NonStop platform. This applies only
  to the NonStop platform guarded by #ifdef __TANDEM.
