Tests whether the file position is at the end of a file. Unit System Category IO routines Delphi syntax: Typed or untyped files: function Eof(var F): Boolean; Text files: function Eof [ (var F: Text) ]: Boolean; Description In Delphi code, Eof tests whether the current file position is the end-of-file. F is a file variable that has been opened for reading. If F is omitted, the standard file variable Input is assumed. Eof(F) returns true if the current file position is beyond the last character of the file or if the file is empty; otherwise, Eof(F) returns false. Note: Eof fails if the file F has been opened in write-only mode. For example, you can’t use Eof with files opened using the Append or Rewrite, which open a file in write-only mode. |

Tests whether the file pointer is at the end of a line. Unit System Category text file routines Delphi syntax: function Eoln [(var F: Text) ]: Boolean; Description In Delphi code, Eoln tests whether the current file position is the end-of-line of a text file. F, if specified, is a text file variable. If F is omitted, the standard file variable Input is assumed. Eoln(F) returns true if the current file position is at an end-of-line or if Eof(F) is true; otherwise, Eoln(F) returns false. |

Returns the end-of-file status of a file, ignoring whitespace. Unit System Category text file routines Delphi syntax: function SeekEof [ (var F: Text) ]: Boolean; Description In Delphi code, call SeekEof to determine whether there is only whitespace between the file pointer and the end of a file. SeekEof moves the file pointer past any whitespace, leaving it positioned at the end of a file or on the next non-whitespace character, whichever comes first. If it leaves the file pointer at the end of the file, SeekEof returns true. Otherwise, it returns false. SeekEof can only be used on open text files. Note: {$I+} handles runtime errors using exceptions. When using {$I-}, use IOResult to check for I/O errors. |
