DESCRIPTION

     The libfsapfs_get_version() function is used to retrieve the library version.

RETURN VALUES

     Most of the functions return NULL or -1 on error, dependent on the return type.  For the
     actual return values see "libfsapfs.h".

ENVIRONMENT

     None

FILES

     None

NOTES

     libfsapfs can be compiled with wide character support (wchar_t).

     To compile libfsapfs with wide character support use: ./configure
     --enable-wide-character-type=yes
      or define: _UNICODE
      or UNICODE
      during compilation.

     LIBFSAPFS_WIDE_CHARACTER_TYPE
      in libfsapfs/features.h can be used to determine if libfsapfs was compiled with wide
     character support.
