In IO::Handle§
See primary documentation in context for method out-buffer
method out-buffer(--> Int) is rw
Controls output buffering and can be set via an argument to open. Takes an int
as the size of the buffer to use (zero is acceptable). Can take a Bool
: True
means to use default, implementation-defined buffer size; False
means to disable buffering (equivalent to using 0
as buffer size).
Lastly, can take a Nil
to enable TTY-based buffering control: if the handle is a TTY, the buffering is disabled, otherwise, default, implementation-defined buffer size is used.
See flush to write out data currently in the buffer. Changing buffer size flushes the filehandle.
