@node accept @section @code{accept} @findex accept POSIX specification:@* @url{https://pubs.opengroup.org/onlinepubs/9699919799/functions/accept.html} Gnulib module: accept Portability problems fixed by Gnulib: @itemize @item On Windows platforms (excluding Cygwin), the descriptors returned by the @code{accept} function cannot be used in calls to @code{read}, @code{write}, and @code{close}; you have to use @code{recv}, @code{send}, @code{closesocket} in these cases instead. @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 third argument type is @samp{int *}. @item On some platforms, this function's third argument type is @samp{void *}, not @samp{socklen_t *}: Solaris 10. @end itemize
