DESCRIPTION¶

The libvsgpt_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 "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.
