GFORTRAN_UNBUFFERED_PRECONNECTED—Do not buffer I/O on preconnected units#
The environment variable named GFORTRAN_UNBUFFERED_PRECONNECTED
controls
whether I/O on a preconnected unit (i.e. STDOUT or STDERR) is unbuffered. If
the first letter is y
, Y
or 1
, I/O is unbuffered. This
will slow down small sequential reads and writes. If the first letter
is n
, N
or 0
, I/O is buffered. This is the default.
