如何激发价值观?结构数组?

我正在尝试在程序开始时初始化此值。我没有得到期望的值,所以指针可能做错了。

Undefined symbols for architecture x86_64:
            "_EVP_aes_256_ctr", referenced from:
                _libssh2_crypt_method_aes256_ctr in liblibssh2_sys-8dfe6494e5de1ded.rlib(crypt.o)

struct TLBentry{
  unsigned int physicalAddress;
  unsigned int virtualAddress;
};

struct pageTableEntry{
  char validFlag;
  char dirty;
  unsigned int physicalAddress;
};

print语句应为“ initialize 1”,但其打印为“ initialize 0”

我不知道发生了什么事。

答案 0 :(得分:0)

您知道C中=和==运算符之间的区别吗?您没有为我的PhysicalAddress分配值i,在此行中什么也没做。

entry->physicalAddress == i;
entry->virtualAddress == i;

在这一行中,为什么要打印tlb [1]?您知道数组在C中从0开始吗?

printf("initialize %d\n", memSys->tlb[1].virtualAddress );
