Adds a new camera to camera list ipCamList if that serial number is not already in the list.
- Parameters
-
ipCamList Pointer to the IpCamList head newItem Pointer to an IpCamList structure that describes the new camera
- Returns
- Returns CAMLIST_ADD_OK if the camera was added to the list, or CAMLIST_ADD_DUP if it was a duplicate.
| void wge100CamListDelAll | ( | IpCamList * | ipCamList | ) |
| int wge100CamListDelEntry | ( | IpCamList * | ipCamList, |
| int | index | ||
| ) |
Utility function to remove a specific element number from the camera list.
- Precondition
- index must be less than the value returned by wge100CamListNumEntries().
- Parameters
-
ipCamList Pointer to the camera list head index Number of the list element to remove (0..max)
- Returns
- Returns 0 if successful, -1 if index was invalid
| int wge100CamListFind | ( | IpCamList * | ipCamList, |
| uint32_t | serial | ||
| ) |
Utility function to return a specific element number from the camera list.
- Precondition
- index must be less than the value returned by wge100CamListNumEntries(). If it is greater, then the last element in the list will be returned.
- Parameters
-
ipCamList Pointer to the camera list head index Number of the list element to returna (0..max)
- Returns
- Returns a pointer to the requested list element
