| + | ======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:====== | ||
| + | <file> | ||
| + | -1 error, no such file descriptor | ||
| + | 0 not at end of file | ||
| + | 1 end of file reached | ||
| + | </file> | ||
