C语言直接画屏（或framebuffer）显示贝塞尔曲线，优化内存的使用。使用时把tmalloc tfree直接修改为malloc free。进一步的优化在于多个malloc合并为一个malloc。也可用于没有OS的嵌入式-C language directly painted screen (framebuffer) shows a Bezier curve, optimizing memory usage. When used directly modify tmalloc tfree to the malloc free in. Further optimization is more than malloc into a malloc. Also be used for embedded OS.
