append => BOOLEAN

create => BOOLEAN

exclusive => BOOLEAN

fh => FILEHANDLE

file => FILENAME|HANDLE

The file to be managed, either provided as FILENAME or as HANDLE. When a HANDLE is passed, most other options will be ignored. The HANDLE must be in non-blocking mode already and opened for writing (only).

mode => '>'|'>>'

The >> is short for normal open plus the append option set.

modeflags => INTEGER

When defined, the mode, exclusive, create and append options are not used, but your value is taken. Use constants defined by Fcntl. Do not forget to include O_NONBLOCK.

name => STRING

write_size => INTEGER
