Where are syscalls located in glibc source

Question

So I was looking through the linux glibc source and I don\'t see where it actually does anything. The following is from io/chdir.c but it is indicative of many

Answer 1

What you've found is a stub function for systems it's not implemented on. You need to look under the sysdeps tree for the actual implementation. The following may be of interest:

• sysdeps/unix/sysv/linux
• sysdeps/posix
• sysdeps/i386 (or x86_64 or whatever your cpu arch is)
