SeekEoln

Declaration:

Function SeekEoln [(Var F : text)] : Boolean;

Description:

SeekEoln returns True is the file-pointer is at the end of the current line. 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-line marker is reached. If the end-of-line marker is reached, True is returned. Otherwise, False is returned.

The end-of-line marker is defined as #10, the LineFeed character.

If the parameter F is omitted, standard Input is assumed.

Errors:

A run-time error is generated if the file F isn't opened.
