- 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
