All C library functions (and most structs, etc.) are documented in
UNIX man pages.
On a BSD-style system (including Mac OS X), these are part of c
library and are linked by default. It looks like on Solaris, you pass
in -l flags for socket and nsl (as others have pointed out).
The command `man inet_addr' produces:
| cc [ flag ... ] file... -lsocket -lnsl [ library...]
| #include <sys/types.h>
| #include <sys/socket.h>
| #include <netinet/in.h>
| #include <arpa/inet.h>
Which tells you 1) the .h files you need to include; 2) any link flags
you must pass to cc; 3) the type defs for the structs; 4) the function
prototypes and behaviors.
I generally have about 5 man pages open when I'm writing in C...
