As RK said.

Often you can find out these kinds of things by searching in your project files for the key word (ctrl+shift+f on my system). When I searched for HVC it quickly led me to the file ble_gatts.h, where there is an enumeration including BLE_GATTS_EVT_HVC. There you will find the following explanation:

/**< Handle Value Confirmation.    \n See @ref ble_gatts_evt_hvc_t.                   */

Then search for ble_gatts_evt_hvc_t and you will find:

/**@brief Event structure for @ref BLE_GATTS_EVT_HVC. */
typedef struct
{
  uint16_t          handle;                       /**< Attribute Handle. */
} ble_gatts_evt_hvc_t;
