Define documentation

#define MAGNUM_ASSERT_GL_VERSION_SUPPORTED(version)

Assert that given OpenGL version is supported.

Parameters
version	Version

Useful for initial checks on availability of required features.

By default, if assertion fails, an message is printed to error output and the application aborts. If CORRADE_NO_ASSERT is defined, this macro does nothing. Example usage:

MAGNUM_ASSERT_GL_VERSION_SUPPORTED(GL::Version::GL330);

#define MAGNUM_ASSERT_GL_EXTENSION_SUPPORTED(extension)

Assert that given OpenGL extension is supported.

Parameters
extension	Extension name (from the Extensions namespace)
