Porting to OS/2: Case #4 socklen_t and macros for shutdown()

socklen_t

When porting network stuffs, you'll often encounter the complains of a compiler about socklen_t. Because OS/2 kLIBC does not define it. So we should define it by ourselves. It's simple. Just use typedef or #define.

1	#define socklen_t int

Or, you can use -D option of gcc.

• gcc some_options -Dsocklen_t=int some_options

Macros for shutdown()

shutdown() uses macros for its argument. Unfortunately, however, OS/2 kLIBC does not have them. They are SHUT_RD, SHUT_WR, and SHUT_RDWR. And they correspond to 0, 1 and 2, respectively. So use #define.
