@node recvfrom @section @code{recvfrom} @findex recvfrom POSIX specification:@* @url{http://www.opengroup.org/onlinepubs/9699919799/functions/recvfrom.html} Gnulib module: recvfrom Portability problems fixed by Gnulib: @itemize @item This function has the return type @code{int} instead of @code{ssize_t} on some platforms: OSF/1 5.1. @item On Windows platforms (excluding Cygwin), error codes from this function are not placed in @code{errno}, and @code{WSAGetLastError} must be used instead. @item On HP-UX 11, in 64-bit mode, when the macro @code{_HPUX_ALT_XOPEN_SOCKET_API} is not defined, this function behaves incorrectly because it is declared to take a pointer to a 64-bit wide @code{socklen_t} entity but in fact considers it as a pointer to a 32-bit wide @code{unsigned int} entity. @end itemize Portability problems not fixed by Gnulib: @itemize @item Some platforms don't have a @code{socklen_t} type; in this case this function's sixth argument type is @samp{int *}. @end itemize
