recvfrom
========

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

Gnulib module: recvfrom

Portability problems fixed by Gnulib:

  * On Windows platforms (excluding Cygwin), error codes for recvfrom 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 sixth argument type is int *.
