Question

I have a DLL written in C, which I must use.
It is ok, but in one place I get an error.

int getHourTime() 
{
   struct tm *psttm;

   time_t timet = //is initialzed correctly

   psttm = localtime(&timet);

   int nHour = psttm->tm_hour;

   return nHour;
}

I am calling it in C# using DLLImport.
When getting to line: “psttm->tm_hour” I get an error (throw) that “Attempted to read or write to protected memory”. I understand that it is because it returns a pointer to an inner place of struct tm, but how can I solve this?

Thanks

Answer 1

The problems was because the next line :

struct tm *psttm;

It was not initialize to NULL.
