In various examples found on the web fgetc() is used like this:
FILE *fp = fopen(PATH, "r");
if (fp == NULL) {
perror("main");
exit(EXIT_FAILURE);
}
int ch;
while (ch = ...

16. feof ....EOF cboard.cprogramming.comThe feof() function tests the end-of-file indicator for the stream pointed to by fp. Because this indicator is set when an input operation attempts to read past the end of the file, the feof() function detects the end of the file only after an attempt is made to read beyond the end of the file. Thus, if a file contains 10 ... |

I do not know any unexpected behaviour related to eof(). But, you could also use Read.good(), which also detects other errors, not just eof. Anyways, I think you should first read from the stream, and then check if the EOF was encountered. If you first check for EOF, and then read, nothing says that the thing you read after the check ... |
Is there any way to set end of file? For example I have a binary file containing 10 records. The end of file will be after 10 records. So if I want to move the eof (end of file) after 5 records, how can I do it? In my view point, if I set the end of file somewhere in the ... |

Also I do not know, what is the code for EOF? How to handle a situation when data would have the same character as the EOF? How ... |
