This function is declared in @code{<winsock2.h>}
|
|
instead of @code{<sys/socket.h>}
|
|
on some platforms:
|
|
mingw, MSVC 14.
|
|
@item
|
|
On Windows platforms (excluding Cygwin), the descriptors returned by
|
|
the @code{socket} 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.
