NAME
libstdbuf —
configure I/O buffers
SYNOPSIS
_STDBUF_[IOE]=size|L…
LD_PRELOAD=/home/nabijaczleweli/code/voreutils/out/lib/libstdbuf.so
DESCRIPTION
If any of _STDBUF_I,
_STDBUF_O, _STDBUF_E
environment variables are set, sets buffering for
stdin, stdout,
stderr
stdio(3) streams, respectively, when loaded.
If the value is L
(l), sets line buffering; otherwise it's taken to be
in the case-insensitive
[base][KMGTPEZY][B]
(with at least one of {base, KMGTPEZY,
B})
format, where base is an optionally-floating-point number
of bytes, defaulting to
1, which is then
optionally multiplied by the relevant unit. B sets the unit
multiplier to
1000 (from
1024). The
buffer size is equal to
, if any, or base. If it works out to
0, buffering is
disabled.
DIAGNOSTICS
Diagnostics are issued to the standard error stream under the
libstdbuf.so identifier if
the buffer specifier is in an invalid format or the buffering couldn't be
set.
