Set file position to end of file
Source position: systemh.inc line 1345
function SeekEOF( |
var t: Text |
):Boolean; |
SeekEof returns True is the file-pointer is at the end of the file. It ignores all whitespace. Calling this function has the effect that the file-position is advanced until the first non-whitespace character or the end-of-file marker is reached.
If the end-of-file marker is reached, True is returned. Otherwise, False is returned.
If the parameter F is omitted, standard Input is assumed.
| Remark: | The SeekEOF function can only be used on real textfiles: when assigning the file to other kinds of (virtual) text files, the function may fail, although it will perform a number of tests to guard against wrong usage. |
A run-time error is generated if the file F isn't opened.
