The example is located in " your_sdk_folder\examples\ble_peripheral\ble_app_hids_mouse ". The sd_ble_gatts_descriptor_add() function is used in e.g. the rep_char_add() function found in ble_hids.c file. 
 The code above is copy-pasted from a random example i made. ble_os_t and char_handle are just residues from that example. ble_os_t is a service struct containing data about the service being worked on and char_handle is the handle to the characteristic that you want to add a descriptor to. If you want to use the code above you will have to modify it a bit to fit your particular application.
