+/* The interface for encryption and decryption is the same. The
+   application must first call the respective init function to
+   initialize the internal state. Then it calls the encrypt/decrypt
+   function repeatedly, as follows: next_in and next_out must point to
+   valid, non-overlapping regions of memory of size at least avail_in
+   and avail_out, respectively. Avail_out must be non-zero. Avail_in
+   may be zero to retrieve some pending output when no input is
+   available, for instance, in an interactive application or at the
+   end of stream. Otherwise, avail_in should be non-zero. 
+
+   The encryption/decryption function will read and process as many
+   input bytes as possible as long as there is room in the output
+   buffer. It will update next_in, avail_in, next_out, and avail_out
+   accordingly. It will always flush as much output as possible.
+   However, it is possible that some input bytes produce no output,
+   because some part of the input may be used for internal purposes.
+   Conversely, it is possible that output is produced without reading
+   any input. When the encryption/decryption function returns, at
+   least one of avail_in or avail_out is 0. If avail_out is non-zero
+   after a call, the application may conclude that no more output is
+   pending.
+
+   Finally, the internal state must be freed by calling the respective
+   end function. This function will discard any unprocessed input
+   and/or output, so it should only be called after the application
+   has retrieved any pending output. Note: the call to the end
+   function should be checked for errors, because this is the only
+   place where certain format errors (like a file that is too short)
+   are detected.
+
+   All functions return 0 on success, or -1 on error with errno set,
+   or -2 on error with ccrypt_errno set. Callers must check for
+   errors. If an error occurs, the state is invalid and its resources
+   are freed. It may not be used again. It is then safe, but not
+   required, to call the corresponding *_end function.
+
+   The flags argument to ccdecrypt_init should be 0 by default, or
+   CCRYPT_MISMATCH if non-matching keys should be ignored. All other
+   values are undefined and reserved for future use.
