read() Netscript Function
|
|
=========================
|
|
|
|
.. js:function:: read(portOrFilename)
|
|
|
|
:RAM cost: 1 GB
|
|
:param string/number portOrFilename: Port or text file to read from.
|
|
|
|
This function is used to read data from a port, a text file (.txt), or a
|
|
script (.script, .js, .ns).
|
|
|
|
If the argument ``portOrFilename`` is a number between 1 and 20, then it
|
|
specifies a port and it will read data from that port. Read about how
|
|
:ref:`netscript_ports` work here. A port is a serialized queue. This
|
|
function will remove the first element from that queue and return it. If the
|
|
queue is empty, then the string "NULL PORT DATA" will be returned.
|
|
|
|
If the argument ``portOrFilename`` is a string, then it specifies the name
|
|
of a text file or script and this function will return the data in the
|
|
specified text file/script. If the text file does not exist, an empty string
|
|
will be returned.
