RETURN VALUES Most of the functions return NULL or -1 on error, dependent on the return type. For the actual return values see "libvsgpt.h". ENVIRONMENT None FILES None NOTES libvsgpt can be compiled with wide character support (wchar_t). To compile libvsgpt with wide character support use: ./configure --enable-wide-character-type=yes or define: _UNICODE or UNICODE during compilation. LIBVSGPT_WIDE_CHARACTER_TYPE in libvsgpt/features.h can be used to determine if libvsgpt was compiled with wide character support.
