C++ (Cpp) _cairo_array_truncate Examples

Example #1

static inline void
_cairo_gl_composite_draw_tristrip (cairo_gl_context_t *ctx)
{
    cairo_array_t* indices = &ctx->tristrip_indices;
    const int *indices_array = _cairo_array_index_const (indices, 0);
    glDrawElements (GL_TRIANGLE_STRIP, _cairo_array_num_elements (indices), GL_UNSIGNED_INT, indices_array);
    _cairo_array_truncate (indices, 0);
}
