9.356 getpeername

POSIX specification:
http://www.opengroup.org/onlinepubs/9699919799/functions/getpeername.html

Gnulib module: getpeername

Portability problems fixed by Gnulib:

• On Windows platforms (excluding Cygwin), error codes for getpeername are not placed in errno, and WSAGetLastError must be used instead.

Portability problems not fixed by Gnulib:

• Some platforms don't have a socklen_t type; in this case this function's third argument type is ‘int *’.
