RETURN_CHECK

#define RETURN_CHECK	(		CONTEXT,
			EXP )

Value:

   do {                                                              \
      const auto result = EXP;                                       \
      if( ! result.isSuccess() ) {                                   \
         ::Error( CONTEXT, XAOD_MESSAGE( "Failed to execute: %s" ),  \
                  #EXP );                                            \
         return result;                                              \
      }                                                              \
   } while( false )

Helper macro for checking return codes in a compact form in the code.

This is pretty much a rip-off of the (ATH_)CHECK macros of the offline code. It is used in the package in functions that return a StatusCode, and themselves call functions returning StatusCode.

Parameters

CONTEXT	A context string to print an error message on failure
EXP	The expression to execute in a checked manner
