Hi,
I have some code that takes a long time to execute. What I would like
to do is to display several real time status messages on the user's
browser as the work is being done (Started doing A ... Done, Started
doing B ... Done, etc). Then once the work is done, I would like to
wipe the status messages and display some results.
I am thinking that I need is something similar to internal redirects,
but I am not sure what. Thanks for any ideas/pointers.
You might try something similiar to webmin with nph scripts we use nph
and local $| in house to do this.
also try using
local $| = 1
HANDLE->autoflush(EXPR)
$OUTPUT_AUTOFLUSH
$| If set to nonzero, forces a flush right away and after every
write or print on the currently selected output channel.
Default is 0 (regardless of whether the channel is really
buffered by the system or not; $| tells you only whether
you've
asked Perl explicitly to flush after each write). STDOUT
will
typically be line buffered if output is to the terminal and
block buffered otherwise. Setting this variable is
useful pri-
marily when you are outputting to a pipe or socket, such as
when you are running a Perl program under rsh and want to see
the output as it's happening. This has no effect on input
buffering. See "getc" in perlfunc for that. (Mnemonic: when
you want your pipes to be piping hot.)
