int emInit (  int  logLevel, int  logType, void(*)(void *ctxt, char *pFile, char *pFunc, int iLine, int level, char *fmt)  cb, void *  ctxt, char *  filename, const char *  name )

Init the Error Manager. Parameters: logLevel  use on of this LOG_DEBUG | LOG_INFO | LOG_NOTICE | LOG_WARNING | LOG_ERR | LOG_CRIT | LOG_ALERT | LOG_EMERG logType  use EM_TYPE_SYSLOG for SYSLOG and EMTYPE_STDERR for stderr cb  callback function for self defined output handling ctxt  user defined data pointer (first parameter for callback function) filename  filename to log to, if not using syslogd name  name of package Returns: the logType or the logLevel or 0 Note: When you do not init, syslog is used. Do not use this function, use the define INIT_STDERR Todo: loggin in a File specific by filename Definition at line 29 of file errmanager.c.
