推荐答案

此符号带有蓝色标题，表示它是SVML的一部分.根据文档要求链接到该符号以获取该符号.

This symbol has a blue header, that means it's part of SVML. Link against it to get the symbol, as the documentation requires it.

然后，SVML将把调用分派到最适合您的体系结构的实现.

SVML will then dispatch the call to the most adequate implementation for your architecture.
