Hi Zoltan
Thanks for answering my query.
This might be a basic question but if pcre_free is a function pointer is
this used to supply a function pointer to the pcre code to be called when
the pcre dll needs to delete the compiled pcre structure returned from
pcre_compile? Am I correct to assume that I need to free the pcre
structure returned by pcre_compile to avoid a memory leak?
The problem I have is C# uses a reserved memory heap or managed heap and I
will have difficulty deleting the pcre structure as it will reside in the
normal unmanaged memory heap. I was thinking of extending the pcre3.dll by
adding an exported C function that will free the structure. As this
function is running outside the unmanaged memory it should be able to free
the structure without a memory access violation . If I try to release the
memory from inside C# I get a memory access violation exception thrown.

I suspect this is incorrect:
private static extern void pcre_free(IntPtr re);
If VPCOMPAT is not defined the symbol is a function pointer not a
function:
PCRE_EXP_DECL void (*pcre_free)(void *);
Although I know nothing of C fence.
