Description

Reads an integer from an open file stream associated with the index FileNum in the file stream resource manager and returns it in i. Returns false if the reading failed or the index FileNum is invalid. The file stream should have been created with OpenFile.

Example

var
  f, i: Integer;

begin
  f := Rewritefile(LogsPath + 'Test.txt', False);
  WriteFileInt(f, 12345);
  CloseFile(f);

  f := OpenFile(LogsPath + 'Test.txt', False);
  ReadFileInt(f, i);
  WriteLn(i);
  CloseFile(f);

  DeleteFile(LogsPath + 'Test.txt');
end.

Output:

12345
