Invalid Pointer

¿Qué significa E_POINTER ?

An invalid pointer was provided to the function. For ProduceXml(), this applies to the output pXML parameter, indicating the variable to store the XML string is not properly allocated. For CreateChild(), this means the pipItem pointer, intended to receive the new child item's interface, is invalid, preventing the successful creation and return of the child item.

• A null pointer was dereferenced in the control software.
• An invalid memory address was accessed.
• A corrupted variable reference points to an uninitialized memory location.

1. 1

   Ensure the output pXML or pipItem parameter is a valid, allocated pointer capable of receiving the expected output (BSTR or ITcSmTreeItem interface).

2. 2

   Check for memory allocation issues in the calling code or improper variable declaration for the output parameter.

3. 3

   Verify the calling environment's COM object handling and pointer management conventions.
