IntPtr	ptr	An unmanaged pointer allocated with MarshalStringArrayToPtr
int	length	The length of the string array.

FreeStringPtr(IntPtr)

Frees a marshalled string that allocated by MarshalStringToPtr.

Declaration

protected static void FreeStringPtr(IntPtr ptr)

Parameters

Type	Name	Description
IntPtr	ptr	An unmanaged pointer allocated with MarshalStringToPtr

string	A System.String with the data from ptr.

MarshalStringArrayToPtr(string[])

Marshals a System.String array to unmanaged memory by calling Marshal.AllocHGlobal for each element.

Declaration

protected static IntPtr MarshalStringArrayToPtr(string[] str_array)

Parameters

Type	Name	Description
string[]	str_array	The string array to marshal.

Returns

Type	Description
IntPtr	An unmanaged pointer to an array of null-terminated strings
