MTA:Eir/FileSystem/file/eof
From Multi Theft Auto: Wiki
This function returns whether the runtime can still read data from the file/stream. This is an implementation defined state that should return false if no data can be immediately received using read operations. Asynchronous file/stream objects could use this function to return true when new data is available to receive from the socket. If wanting to read an entire file/stream object, this function is more reliable than the file.size approach.
Syntax
boolean file.eof ()
Returns
Returns true if data is available to be read from the file/stream object. Return false if data is not immediately available to receive from it.

ClientThis snippet is guaranteed to read an entire file/stream object.
local fileGetContentSafe( theFile )
-- Allocate a string buffer where all information is saved in.
local buffer = "";
-- Read from the stream until it cannot anymore.
while not ( theFile.eof() ) do
buffer = buffer .. theFile.read( 1024 );
end
-- At this point, some implementations could wait for data.
-- Implementations are advised to use blocking I/O, implement additional Lua functions or throw exceptions.
-- Clean up the file/stream handle and return the result buffer.
theFile.destroy();
return buffer;
end
