## Detailed Description

This class can be used to redirect the log messages to a C file stream (not to be confused with C++ streams).

It is the default log target for the non-GUI wxWidgets applications which send all the output to `stderr`.

## Public Member Functions

| wxLogStderr (FILE *fp=NULL)
| Constructs a log target which sends all the log messages to the given `FILE`. More...
Public Member Functions inherited from wxLog
wxLogFormatter * | SetFormatter (wxLogFormatter *formatter)
| Sets the specified formatter as the active one. More...
virtual void | Flush ()
| Some of wxLog implementations, most notably the standard wxLogGui class, buffer the messages (for example, to avoid showing the user a zillion of modal message boxes one after another – which would be really annoying). More...
void | LogRecord (wxLogLevel level, const wxString &msg, const wxLogRecordInfo &info)
| Log the given record. More...

| Remove the mask from the list of allowed masks for wxLogTrace(). More...
static void | DontCreateOnDemand ()
| Instructs wxLog to not create new log targets on the fly if there is none currently (see GetActiveTarget()). More...
static wxLog * | GetActiveTarget ()
