Function Documentation

void report_current_exception (  const int  line, const char *  file )  throw ()

Helper function for REPORT_CURRENT_EXCEPTION macro. Definition at line 315 of file log.C. References rutz::demangled_name(), and e.

void sendlog (  const char *  msg,   ... )

Send a log. NON-GNUC, thread-unsafe version. Definition at line 256 of file log.C. References i, LBS, LBS2, LOG_FLAGS, MYLOG_USEID, MYLOG_USEP, MYLOGFIL, MYLOGFUN, MYLOGIDVAL, MYLOGLEV, MYLOGLIN, MYLOGVERB, sendlog_aux(), snprintf(), and vsnprintf().

void @0::sendlog_aux (  const char *  raw_msg, const int  level, const int  flags )  [static]

A little helper function for sendlog(). This avoids duplicating the flag-parsing logic between our two versions of sendlog(). Definition at line 93 of file log.C. References rutz::error_context::current(), LFATAL_PRINTS_ABORT, LFATAL_THROWS, LFATAL_XTRA_NOISY, LOG_FULLTRACE, aux::msg(), MYLOGPREFIX, and rutz::error_context::prepend_to(). Referenced by sendlog().

Variable Documentation

int LOG_FLAGS

Initial value: (LFATAL_THROWS | LFATAL_PRINTS_ABORT | LFATAL_XTRA_NOISY | LOG_FULLTRACE) Bitwise-or'ed combination of above flags. Definition at line 56 of file log.C. Referenced by main(), mexFunction(), and sendlog().

const char* MYLOGPREFIX = 0

Null by default, but if set to non-null this string will be prefixed to every log message. This can be useful if you have multiple threads or multiple processes all writing to stdout, and you want to have some way to distinguish their log messages. Definition at line 66 of file log.C. Referenced by handlesignal(), run_master(), run_slave(), and sendlog_aux().

int MYLOGVERB = LOG_INFO

Log verbosity (see <syslog.h> for possible values). Default value is LOG_DEBUG. Executables don't need to do anything special unless they need a non-default value.
