C 如何将切片发送到Go中的函数？

我正在用Go重写一些C代码。在我的C代码中，我有如下内容：

static void sharedb(unsigned char *sharedkey, unsigned char *send,
                    const unsigned char *received) {
    unsigned char krq[96]; 
    unsigned char buf[64];
    // rest removed for brevity

    indcpa_enc(send, buf, received, krq + 32);
}

static void indcpa_enc(unsigned char *c,
                       const unsigned char *m,
                       const unsigned char *pk,
                       const unsigned char *coins)

func SharedB(sharedKey, send, received []byte) {
    var krq [96]byte
    var buf [64]byte

    // rest removed for brevity

    INDCPAEnc(send[:], buf[:SharedKeyBytes], received[:], krq[32:32+CoinBytes])
}

func INDCPAEnc(c []byte, m [SharedKeyBytes]byte, pk []byte, coins [CoinBytes]byte) 

其中

indcpa\u enc

函数定义如下：

static void sharedb(unsigned char *sharedkey, unsigned char *send,
                    const unsigned char *received) {
    unsigned char krq[96]; 
    unsigned char buf[64];
    // rest removed for brevity

    indcpa_enc(send, buf, received, krq + 32);
}

static void indcpa_enc(unsigned char *c,
                       const unsigned char *m,
                       const unsigned char *pk,
                       const unsigned char *coins)

func SharedB(sharedKey, send, received []byte) {
    var krq [96]byte
    var buf [64]byte

    // rest removed for brevity

    INDCPAEnc(send[:], buf[:SharedKeyBytes], received[:], krq[32:32+CoinBytes])
}

func INDCPAEnc(c []byte, m [SharedKeyBytes]byte, pk []byte, coins [CoinBytes]byte) 

因此，在我的Go代码中，我没有使用

char

数组，而是使用

byte

数组。我有这样的东西：

static void sharedb(unsigned char *sharedkey, unsigned char *send,
                    const unsigned char *received) {
    unsigned char krq[96]; 
    unsigned char buf[64];
    // rest removed for brevity

    indcpa_enc(send, buf, received, krq + 32);
}

static void indcpa_enc(unsigned char *c,
                       const unsigned char *m,
                       const unsigned char *pk,
                       const unsigned char *coins)

func SharedB(sharedKey, send, received []byte) {
    var krq [96]byte
    var buf [64]byte

    // rest removed for brevity

    INDCPAEnc(send[:], buf[:SharedKeyBytes], received[:], krq[32:32+CoinBytes])
}

func INDCPAEnc(c []byte, m [SharedKeyBytes]byte, pk []byte, coins [CoinBytes]byte) 

其中，

INDCPAEnc

函数的定义如下：

static void sharedb(unsigned char *sharedkey, unsigned char *send,
                    const unsigned char *received) {
    unsigned char krq[96]; 
    unsigned char buf[64];
    // rest removed for brevity

    indcpa_enc(send, buf, received, krq + 32);
}

static void indcpa_enc(unsigned char *c,
                       const unsigned char *m,
                       const unsigned char *pk,
                       const unsigned char *coins)

func SharedB(sharedKey, send, received []byte) {
    var krq [96]byte
    var buf [64]byte

    // rest removed for brevity

    INDCPAEnc(send[:], buf[:SharedKeyBytes], received[:], krq[32:32+CoinBytes])
}

func INDCPAEnc(c []byte, m [SharedKeyBytes]byte, pk []byte, coins [CoinBytes]byte)

尽管如此，Go中的这个函数调用给了我一个关于类型不匹配的数组。如何将上面的C代码转换为正确的Go代码？此外，我是否应该像在C中一样使用指针符号

*

作为我的Go函数参数？

指定长度的参数（例如

[SharedKeyBytes]byte

）是数组，而不是片；因此，无法传递切片，因此会出现类型不匹配错误。您可以：

• 将参数类型更改为slice（

  []字节

  ）
• 在调用函数之前，将切片复制到适当大小的数组中，然后将数组传递给函数，而不是切片（）
