C++ deprecated conversion from string constant to ‘char*’

我有以下代码，虽然我没有复制完整的代码，因为它是巨大的。
以下代码在模板类中，我收到如下警告。由于模板中的警告，我无法实例化它并获得从这里实例化错误。

I am having following code, though i didn't copy full code because it is huge. Following code is in template class, and i am getting warning as below. Because of warning in template i am not able to instantiate it and getting "instantiated from here" error.

警告：不推荐从字符串常量转换至'char *''

warning: deprecated conversion from string constant to 'char*''

void ErrorMessageInRaphsodyCode(char* pcCompleteMessage, char* pcMessage, char* pcFileName, unsigned int RowNo)
{
//...
}


char cCompleteMessage[200];
memset(cCompleteMessage, 0x00, sizeof(cCompleteMessage));
char*cMessage = "add reorgenize failed";
ErrorMessageInRaphsodyCode(cCompleteMessage, cMessage, "omcollec.h", __LINE__);

我的问题是什么是最好的方法来摆脱上述警告？

My question is what is best way to get rid of above warning ?

推荐答案

如果函数接受 char const * ，它保证它只读取指针指着。但是，如果它使用一个非常量指针，如 char * ，它可能会写入。

If a function takes a char const *, it guarantees that it only reads whatever data the pointer points to. However, if it takes a non-const pointer, like char *, it might write to it.

写入字符串字面值是不合法的，编译器将发出警告。

As it is not legal to write to a string literal, the compiler will issue a warning.

最好的解决方法是更改​​函数接受 char const * 而不是 char * 。

The best solution is to change the function to accept char const * rather than char *.
