Obtain the number of bytes that can be read from handle without blocking.$ available($handle, "delim")
Read ahead in the handle to see if the delimeter is present in the buffer or not.
$handle - the handle to check. if no handle is specified the console will be used.
"delim" - the delimeter to search for.
In the first usage, the number of bytes readable from the handle without blocking. In the second case $null is returned if the delimeter is not found. Otherwise the position of the delimeter is returned.
$handle = connect("www.yahoo.com", 80); println($handle, "GET /"); sleep(3000); println(available($handle) . " bytes are available");
