__NOTOC__
This function attempts to read an integer (native type) from a file and return it. The amount of bytes read should be four.

==Syntax==
<syntaxhighlight lang="lua">
int file:readInt ()
</syntaxhighlight>

==Returns==
Returns an integer if it was successfully read from the file, '''false''' otherwise.

==Example==
<section name="Client" class="client" show="true">
This snippet demonstrates an encrypted Lua source code format.
<syntaxhighlight lang="lua">
-- Have some pieces of source code as samples.
local sourceSamples = {

-- Encrypt the source code.
local encryptedCode = teaEncode( sourceString );

-- Write the file header.

-- Write file contents.

-- Grab the source code from the file.
