eof

Synopsis:

$eof(«file descriptor»)

Technical:

This function tests whether the client is currently at the end of the file pointed to by the given file descriptor. The only valid input is a file descriptor returned by the $open() function.

Practical:

This function is used to see if the end of a file has been reached. This is mostly useful while reading a file, such that it can be closed once the end is reached.

Returns:

-1   error, no such file descriptor
 0   not at end of file
 1   end of file reached
