Notes and code from APUE (Advanced Programming in the Unix Environment, 2nd Edition).

The book can be found here.

Source code can be found here.

/APUE/apue.2e (compiled source code)

/APUE/chx (my notes for chapter x)

I have compiled the source code on MAC. Suppose you just obtain the source code, then follow the [instrctions] (https://github.com/y-c/APUE/blob/master/apue.2e/README) to compile. If you are using MAC and it complains:

Undefined symbols for architecture x86\_64:
  "_CMSG_LEN", referenced from:
        _recv_fd in libapue.a(recvfd.o)
        ld: symbol(s) not found for architecture x86_64
        clang: error: linker command failed with exit code 1 (use -v to see invocation) 

Simply adding -D\_DARWIN\_C\_SOURCE into Make.defines.macos will resolve the issue.

Suppose you have written your own file.c in the folder APUE/ch1, go to the folder and

gcc -o a file.c -L. ../apue.2e/lib/libapue.a
