On a MacOS system, you can find them in /usr/include/sys/errno.h
On a Linux system, try /usr/include/asm-generic/errno.h

However, if you're writing in Python, you will probably have an easier 
time using the "errno" module, e.g., 

 ] import errno
 ] errno.errorcode[35]
 'EDEADLOCK'

Note that some codes have multiple names (e.g., EAGAIN and EWOULDBLOCK) 
so that this lookup may not return exactly the name you're expecting.
