FreeMem question
xinyiman:
I own a string in memory allocated by a DLL written in C and assigned to a PChar the ShowMessage () I can see correct values. The only thing I can do is to free the memory area occupied. So I decided to use the passing FreeMem PChar but I SIGSERV returns an error. Does anyone know how to address the problem? :)

You can't free the memory allocated by a DLL. The DLL must do it.

Ok, I had thought about but I can not get it, I PChar the revision to a hypothetical function that is called
void LiberaStringa(char * variabile)
{
free(variabile);
}
But it works!

If the function is in the DLL, then it works. Yes. It has a different memory manager and address space than your program.

I can not understand, but does not work, it is a dll that I'm writing with devcpp. And your last message is not clear!
