std::feof - cppreference.com (original) (raw)
Checks if the end of the given file stream has been reached.
[edit] Parameters
| stream | - | the file stream to check |
|---|
[edit] Return value
Nonzero value if the end of the stream has been reached, otherwise 0.
[edit] Notes
This function only reports the stream state as reported by the most recent I/O operation, it does not examine the associated data source. For example, if the most recent I/O was a std::fgetc, which returned the last byte of a file, std::feof returns zero. The next std::fgetc fails and changes the stream state to end-of-file. Only then std::feof returns non-zero.
In typical usage, input stream processing stops on any error; feof and std::ferror are then used to distinguish between different error conditions.
[edit] Example
Output:
End of file reached successfully
