is not NULL it should be of type (int *).
returns a socket BIO using sock
Socket BIOs also support any relevant functionality of file descriptor BIOs.
The reason for having separate file descriptor and socket BIOs is that on some
platforms sockets are not file descriptors and use distinct I/O routines,
Windows is one such platform. Any code mixing the two will not work on all
