#define Assure_exit (  exp_   )

Value: do { \ if ( !(exp_) ) { \ DL((ASSA::ASSAERR,"Assure Aborted False Expression!\n")); \ DL((ASSA::ASSAERR,"Error on line %d in file %s\n", __LINE__, __FILE__)); \ ::raise( SIGTERM ); \ } \ } while (0) Macro that makes program exit if assert fails. assert a la ASSA. If expression exp_ is evaluated to false, error message is logged and current process is terminated with SIGTERM signal. Parameters: exp_  expression to evaluate Definition at line 39 of file Assure.h. Referenced by ASSA::Semaphore::close(), ASSA::Semaphore::create(), ASSA::FileLogger::handle_rollover(), ASSA::RemoteLogger::log_msg(), ASSA::Semaphore::op(), ASSA::Semaphore::open(), and ASSA::Semaphore::remove().

#define Assure_return (  exp_   )

Value: do { \ if ( !(exp_) ) { \ DL((ASSA::ASSAERR,"Assure Returned False Expression!\n")); \ DL((ASSA::ASSAERR,"Error on line %d in file %s\n", __LINE__, __FILE__)); \ return (false); \ } \ } while (0) Test condition and return bool from a function if assertion fails. Expression exp_ is evaluated and tested for the truth. If expression is false, error message with file name and line number is logged to the log file, and program control is returned back from current execution scope with return value equal to FALSE. Parameters: exp_  expression to evaluate Returns: FALSE if expression evaluates to false; if expression happens to evaluate to TRUE, Assure_return() DOES NOT return - program continues its natural execution flow.

#define Assure_return_value (  exp_, value_   )

Value: do { \ if ( !(exp_) ) { \ DL((ASSA::ASSAERR,"Assure Returned False Expression!\n")); \ DL((ASSA::ASSAERR,"Error on line %d in file %s\n", __LINE__, __FILE__)); \ return (value_); \ } \ } while (0) Test condition and return value_ from a function if assertion fails. Expression exp_ is evaluated and tested for the truth. If expression is false, error message with file name and line number is logged to the log file, and program control is returned back from current execution scope with return value equal to value_. Parameters: exp_  expression to evaluate value_  value to return Returns: value_ if expression evaluates to false; if expression happens to evaluate to TRUE, Assure_return_value() DOES NOT return - program continues its natural execution flow. Definition at line 109 of file Assure.h.

#define Assure_return_void (  exp_   )

Value: do { \ if ( !(exp_) ) { \ DL((ASSA::ASSAERR,"Assure Returned False Expression!\n")); \ DL((ASSA::ASSAERR,"Error on line %d in file %s\n", __LINE__, __FILE__)); \ return; \ } \ } while (0) Test condition and return from a function immediately if assertion fails. Expression exp_ is evaluated and tested for the truth. If expression is false, error message with file name and line number is logged to the log file, and program control is returned back from current execution scope. Parameters: exp_  expression to evaluate Definition at line 84 of file Assure.h.
