macos - Where is the standard C library on Mac OS X?

Question

I am trying to find the standard C library on Mac OS X. I've tried paths like: "/usr/lib/libc.a" or "/usr/lib/libm.a" , but there are no such files on the system. Could you tell me where to find it?

Then I used Terminal at a Linux machine and run such command:

ar t /usr/lib/libc.a

It returns a list of .o files and those .o files are like these:

svc.o
xdr.o
...

What are the meanings of these files? where to find them?

Answer 1

The standard library is part of libSystem.dylib on OS X.
