memcpy problem

[krishnasamy]

Hi,

I have problem with copy the bitmap* to char* using memcpy.

Here I given my code,

char* cbuffer;
int size = 240000;
Bitmap *bitmap = new Bitmap(L"Image. bmp");
bitmap->Rotate(RotateN oneFlipX);
memcpy(cbuffer, bitmap,size);

FILE *fptr;
fptr = fopen("image2.b mp","wb");
fwrite(cbuffer, 1,size,fptr);
fclose(fptr);

In My above code, the image2.bmp has not saving.

What is the problem?

Whay i am asking this is, you havent allocated any memory for the cbuffer.

Thanks for your reply.

Above code is not working proberly. Actually this code was created through DLL. I checked with my exe but the image was not creating.

How I allocated the memory to char buffer.

Is there any option in c++ or vc++?

Are you aware of malloc/calloc/new in C++ or in C.
You have to start reading that before using it
