 * cpl_vsi.h
 *
 * Include file defining the Virtual System Interface (VSI) functions.  This
 * should normally be included by all translators using VSI functions for
 * accessing system services.  It is also used by the GDAL core, and can be
 * used by higher level applications which adhere to VSI use.
 *
 * Most VSI functions are direct analogs of Posix C library functions.
 * VSI exists to allow ``hooking'' these functions to provide application
 * specific checking, io redirection and so on. 
 * 
 * $Log: cpl_vsi.h,v $
 * Revision 1.4  1999/02/25 04:48:11  danmo
 * Added VSIStat() macros specific to _WIN32 (for MSVC++)
 *
 * Revision 1.3  1999/01/28 18:31:25  warmerda
 * Test on _WIN32 rather than WIN32.  It seems to be more reliably defined.
 *
 * Revision 1.2  1998/12/04 21:42:57  danmo
 * Added #ifndef WIN32 arounf #include <unistd.h>
 *
 * Revision 1.1  1998/12/03 18:26:02  warmerda
