 If the hiprtcLinkComplete returns successfully, the generated binary can be loaded and run using the hipModule* APIs.
 ```cpp
-hipModuleLoadData( &module, binary );
+hipModuleLoadData(&module, binary);
 ```
 
 #### Note
  - The compiled binary must be loaded before hiprtc link instance is destroyed using the hiprtcLinkDestroy API.
 ```cpp
-hiprtcLinkDestroy( rtc_link_state);
+hiprtcLinkDestroy(rtc_link_state);
 ```
  - The correct sequence of calls is : hiprtcLinkCreate, hiprtcLinkAddData or hiprtcLinkAddFile, hiprtcLinkComplete, hiprtcModuleLoadData, hiprtcLinkDestroy.

 ## Error Handling
 HIPRTC defines the hiprtcResult enumeration type and a function hiprtcGetErrorString for API call error handling.  hiprtcResult enum defines the API result codes.  HIPRTC APIs return hiprtcResult to indicate the call result. hiprtcGetErrorString function returns a string describing the given hiprtcResult code, e.g., HIPRTC_SUCCESS to "HIPRTC_SUCCESS". For unrecognized enumeration values, it returns "Invalid HIPRTC error code".
