BloombergLP::ball::AsyncFileObserver::setLogFormats

Set the format specifications for log records written to the log file and to stdout to the specified logFileFormat and stdoutFormat, respectively. If the default short output format is currently in effect for logging to stdout, this method has the effect of calling enableStdoutLoggingPrefix (see that method and disableStdoutLoggingPrefix) and setting the format corresponding to enabled stdout logging prefix to stdoutFormat. See {Log Record Formatting} for details on the syntax of format specifications. Return zero if both formats are valid and have been set. Otherwise, if either format is invalid return a non-zero value. If one of the formats is invalid it will not be set, but the valid format will. Note that default formats are in effect following construction until a format-setting method is called ("n%d %p:%t %s %f:%l %c %m %un" for both file and stdout logging).
