7 Gnulib module: recvfrom
9 Portability problems fixed by Gnulib:
12 This function has the return type @code{int} instead of @code{ssize_t}
16 On Windows platforms (excluding Cygwin), error codes from this function
17 are not placed in @code{errno}, and @code{WSAGetLastError} must be used
20 On HP-UX 11, in 64-bit mode, when the macro @code{_HPUX_ALT_XOPEN_SOCKET_API}
21 is not defined, this function behaves incorrectly because it is declared
22 to take a pointer to a 64-bit wide @code{socklen_t} entity but in fact
23 considers it as a pointer to a 32-bit wide @code{unsigned int} entity.
26 Portability problems not fixed by Gnulib:
29 Some platforms don't have a @code{socklen_t} type; in this case this function's
30 sixth argument type is @samp{int *}.
