| Argument | Type | Description |
| cConnections | ULONG | [in] Specifies the number of IConnectionPoint * values to return in the array pointed to by rgpcn. This argument must be 1 if pcFetched is NULL. |
| rgpcn | IConnectionPoint ** | [out] A pointer to a caller-allocated IConnectionPoint * array of size cConnections in which to return the enumerated connection points. The caller is responsible for calling IConnectionPoint::Release through each pointer enumerated into the array once this method returns successfully. If cConnections is greater than one the caller must also pass a non-NULL pointer passed to pcFetched to know how many pointers to release. |
| pcFetched | ULONG | [out] A pointer to the variable to receive the actual number of connection points enumerated in rgpcn. This argument can be NULL in which case the cConnections argument must be 1. |
| Return Value | Meaning |
| S_OK | The requested number of elements has been returned and *pcFetched (if non-NULL) is set to cConnections if. |
| S_FALSE | The enumerator returned fewer elements than cConnections because there were not that many elements left in the list. In this case, unused elements in rgpcn in the enumeration are not set to NULL and *pcFetched holds the number of valid entries, even if zero is returned. |
| E_POINTER | The address in rgpcn is not valid (such as NULL). |
| E_INVALIDARG | The value of cConnections is not 1 when pcFetched is NULL; or the value of cConnections is zero. |
| E_UNEXPECTED | An unknown error occurred. |
| E_OUTOFMEMORY | There is not enough memory to enumerate the elements. |
