eof
Synopsis:
$eof(
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
