Hi! Is this a proper use of a strings vector?

#define SAFE_DELETE_FIELD(ob) if(ob) {delete[] ob; ob = NULL;} 

// In a class I have this STL vector with char pointers

std::vector <char*> m_vObjectNames;

// Somewhere in a func in the code I do this:

char *Name;
Name = new char[ 1 + (mChunk->mBytes)];
strcpy(Name, (char *)mBuffer);

// I can´t remove Name now

// becuase m_vObjectNames[curr_element] 

// use this memory

// In the destructor I remove the memory

int NumberOfString = m_vObjectNames.size();

for(int i=0; i<NumberOfString; i++)


Thanks, Zeblar Nagrim, Lord of Chaos

the code is ok, but

You should actually be using std::string. that way you don`t need to worry about memory allocation and deallocation.


#include <strings>
#include <vector>

//later in the code ....

std::vector<std::string> myStrVector;

std::string myFirstString = "hello";

myStrVector.push_back( myFirstString );

//later for destruction...

//nothing to do!!!!!!! string destructor will free the memory of the strings and vector will clean up itself.

This is actually very efficient, because most implementation of the stl string uses reference counted pointers, so when you push_back the string, the only thing that is copied is actually an internal pointer.
