[Xen-devel] Questions about LOG system

[ææå <Chunqi Li> <yzt356@xxxxxxxxx>]

Hi all,

When I'm reading code of Xen and I can't find the exact LOG file written by each log-writing code, so I have some trouble with debugging.

I have found 8 type of LOG managed by xen-4.0 or later, 

#define LOG_EMERG 0

#define LOG_ALERT 1

#define LOG_CRIT 2

#define LOG_ERR 3

#define LOG_WARNING 4

#define LOG_NOTICE 5

#define LOG_INFO 6

#define LOG_DEBUG 

and there are three frequently used macro for logging:

#define DPRINTF(_f, _a...) syslog(LOG_INFO, _f, ##_a)

#define EPRINTF(_f, _a...) syslog(LOG_ERR, "tap-err:%s: " _f, __func__, ##_a)

#define  PERROR(_f, _a...) syslog(LOG_ERR, "tap-err:%s: " _f ": %s", __func__, ##_a, \

 strerror(errno)

Who can tell me which file match these log type above? Thank you.
