Function Documentation

int a_Logging_redirect (  XetPan *  xetpan, const char *  path )

Redirect standard error to a log file. This is done because many GUI application launchers do not show the user the standard error even if the application did not start. Makes a backup of the old log file if it existed. Parameters: path  a directory where the log file will be created. Returns: 0 on success, system's errno otherwise.

Here is the call graph for this function:

Variable Documentation
