On success, these functions return the number of input items successfully matched and assigned; this can be fewer than provided for, or even zero, in the event of an early matching failure.
The value EOF is returned if the end of input is reached before either the first successful conversion
or a matching failure occurs. EOF is also returned if a read error occurs, in which case the error
indicator for the stream (see ferror(3)) is set, and errno is set to indicate the error.
