If an error occurs, or if the end of the file stream is reached before the first conversion, the return value is EOF for fscanf_s and fwscanf_s.These functions validate their parameters. If stream is an invalid file pointer, or format is a null pointer, these functions invoke the...
(with the _s suffix) and the older functions is that the secure functions require the size in characters of each c, C, s, S and [ type field to be passed as an argument immediately following the variable.For more information, see scanf_s, _scanf_s_l, wscanf_s, _wscanf_s_...
