accept (GNU Gnulib)

Gnulib module: accept

Portability problems fixed by Gnulib:

This function is declared in <winsock2.h> instead of <sys/socket.h> on some platforms: mingw, MSVC 14.
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 from this function are not placed in errno, and WSAGetLastError must be used instead.
On HP-UX 11, in 64-bit mode, when the macro _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 socklen_t entity but in fact considers it as a pointer to a 32-bit wide unsigned int entity.

Portability problems not fixed by Gnulib:

Some platforms don’t have a socklen_t type; in this case this function’s third argument type is ‘int *’.
On some platforms, this function’s third argument type is ‘void *’, not ‘socklen_t *’: Solaris 10.
