static member SecureStringToBSTR : System.Security.SecureString -> nativeint[<System.Security.SecurityCritical>]
static member SecureStringToBSTR : System.Security.SecureString -> nativeintPublic Shared Function SecureStringToBSTR (s As SecureString) As IntPtrParameters
The managed object to copy.
Returns
nativeint
The address, in unmanaged memory, where the s parameter was copied to, or 0 if a null object was supplied.

Exceptions
The s parameter is null.
There is insufficient memory available.
Remarks
The SecureStringToBSTR method is useful for custom marshaling or when mixing managed and unmanaged code. Because this method allocates the unmanaged memory required for a string, always free the BSTR when finished by calling the ZeroFreeBSTR method.
