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?

The <stdio. h> header file is part of the C standard library, and may be in any directory that the compiler searches for header files, it may be in a sub-directory to /usr/lib for example. Also, the command find ./ -iname "stdio.
Library. This folder contains fonts and other items used by apps that are available to all users of your Mac. Don't use this folder to store files and folders you create. Instead, use the home folder, the Desktop folder, the Documents folder, or iCloud Drive.
The library files (. a, . dylib, etc) will go into /usr/local/lib while the header files will all go into /usr/local/include. In order to get the compiler to look into those directories when compiling, you need to specify them.
This form is used when the header file is located in the directory /usr/include/ directory , where directory is a subdirectory of /usr/include. #include " headername . h" This form is used when the header file is located in a user or nonstandard directory.
The standard library is part of libSystem.dylib on OS X.
