如何从valgrind中抑制openssl

我正在使用openssl库。 我从valgrind那里得到很多警告

有什么方法可以禁止valgrind发出此警告吗？

如果可以重建openssl，可以使用-DPURIFY来消除这些警告，请参阅openssl。@ks1322那么我是否需要使用-DPURIFY only valgrind进行编译，或者在发布版本中使用目标库没有问题。是，openssl使用未初始化的缓冲区来生成随机数，这是正常的，这就是Valgrind所抱怨的-DPURIFY应仅用于调试，例如不要错过其他Valgrind警告。解释了如何使用Valgrind的API进行测试，但我自己还没有测试过
