structures, pointers to structures, and the write() member function

Hello Everyone!!!

I have a serious problem. I know this may sound a bit amateurish, but I am really stuck. I have a dynamically allocated array of structures, and have to print it to a file using binary output. The problem is I keep getting a "Stack Exception" error in the "Write(1)...memorey address". Here is my current code:

outbin.write((char *)studRecPtr, sizeof(studRecPtr[loopIt]));

Any help would be highly appreciated. Thank you.

You could try:

outbin.write((char*)studRecPtr, NrOfStructs * sizeof(STRUCTBASE));

if you have typedef:ed your struct

typedef struct
{
...
}STRUCTBASE;

STRUCTBASE* studRecPtr;

how does this write function work?
what header?

fstream.h, I believe...

Try:

outbin.write((char *)studRecPtr[loopIt], sizeof(studRecPtr[loopIt]));

i figured it out!!!!!! thanks for your help!!!!!
