Copying NOT null terminated C-string to std::string

Hi *!
I get from a lib a not null-terminated string back. I am want to copy it to my local std::string. I also get back the total length of C-string. Here is what i am doing

PHP Code:

---

char* pChr = NULL;
short  nChrLen = 0;
std::string szMyString = "";
// Call some lib functions with pChr and &nChrLen....
if(pChr){
      szMyString = pChr;
      szMyString[nChrLen] = '\\0';
} 


---

It works correctly but is it the corrrect way, coz if i don't null terminate the string i get some junk stuff (thats obvious) but the copying of string reads some part of memory that it is not supposed to. Whats the correct way to do that????????
Thanks in Advance,
Regards,
Usman.

Use the std::string::assign() member function:

Code:

---

szMyString.assign(pChr, nChrLen);

Why don't u try null terminating the char* and then assign it?

Because std::string::assign exists.

Well as i earlier described in my post that memory is not allocated in my program. I dont want to modify that memory that i dont know of.
