   1 /*
   2  * this is an internal header file - the structure contains two off_t
   3  * atleast making it LARGEFILE_SENSITIVE on linux2 and solaris systems
   4  * whereas about all functions just return a ZZIP_FILE* in zzip/zzip.h
   5  *
   6  * and so, this structure should be handled version-specific and
   7  * subject to change - it had been kept binary-compatible for quite
   8  * a while now so perhaps some program sources have errnously taken
   9  * advantage of this file.
