FileRead
From Multi Theft Auto: Wiki
Reads the specified number of bytes from the given file starting at its current read/write position, and returns them as a string.
Syntax
string fileRead ( file theFile, int count )
OOP Syntax Help! I don't understand this!
- Method: file:read(...)
Required Arguments
- theFile: A handle to the file you wish to read from. Use fileOpen to obtain this handle.
- count: The number of bytes you wish to read.
Returns
Returns the bytes that were read in a string. Note that this string might not contain as many bytes as you specified if an error occured, i.e. end of file.
Example
This example opens the file test.txt and outputs its contents to the console.
function readFile(path)
local file = fileOpen(path) -- attempt to open the file
if not file then
return false -- stop function on failture
end
local count = fileGetSize(file) -- get file's total size
local data = fileRead(file, count) -- read whole file
fileClose(file) -- close the file once we're done with it
outputConsole(data) -- output code in console
end
addCommandHandler("readfile",function(cmd,fileName) -- add command to test this function
readFile(fileName) -- execute the function
end)
fileOpen sets the read/write position to the beginning of the file. fileGetSize gets the total size in bytes of given file.
