9.14 accept

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

Gnulib module: accept

Portability problems fixed by Gnulib:

• On Windows platforms (excluding Cygwin), the descriptors returned by the accept function cannot be used in calls to read, write, and close; you have to use recv, send, closesocket in these cases instead.
• On Windows platforms (excluding Cygwin), error codes for accept are not placed in errno, and WSAGetLastError must be used instead.

Portability problems not fixed by Gnulib:

• On BeOS, the descriptors returned by the accept function cannot be used in calls to read, write, and close; you have to use recv, send, closesocket in these cases instead.
• Some platforms don't have a socklen_t type; in this case this function's third argument type is ‘int *’.
