*
* Opening a file with read mode ('r' as the first character in the mode

* Opening a file with append mode ('a' as the first character in the mode
* argument) causes all subsequent writes to be forced to the current end of

* implementations, opening a binary file with append mode ('b' as the

* the file position indicator beyond the last data written, because of the
* NUL padding.
* When a file is opened with update mode ('+' as the second or third
* character in the mode argument), both input and output may be performed
* on the associated stream. However, output may not be directly followed
* by input without an intervening call to the fflush fuction or to a file
* positioning function (fseek, fsetpos, or rewind), and input be not be
* directly followed by output without an intervening call to the fflush
* fuction or to a file positioning function, unless the input operation
* encounters end-of-file. Opening a file with update mode may open or
* create a binary stream in some implementations. When opened, a stream
* is fully buffered if and only if it does not refer to an interactive
* device. The error and end-of-file indicators for the stream are
* cleared.
* Returns: a pointer to the object controlling the stream. If the open
