I am trying to understand how asl.h works, while I am reading asl.h According to http://www.opensource.apple.com/source/Libc/Libc-583/include/asl.h comment of this method. 

aslclient asl_open(const char *ident, const char *facility, uint32_t opts);

It is said "Initialize a connection to the ASL server." I am wondering what is ASL server in this case.

Thanks

The first place to look for details on using ASL is the manpage, which you can pull up in Terminal using the command:

man 3 asl

Beyond that, Peter Hosey's Idle Time website has a number of posts detailing how ASL works.

For people wishing to use ASL from a Swift-based API, there's the CleanroomASL open-source project, which also has more details about differences between how ASL works on iOS devices and the Mac.
