DDDDEEEESSSSCCCCRRRRIIIIPPPPTTTTIIIIOOOONNNNBIO_s_socket() returns the socket BIO method. This is a
wrapper round the platform's socket routines.BIO_read() and BIO_write() read or write the underlying
socket. BIO_puts() is supported but BIO_gets() is not.
If the close flag is set then the socket is shut down and closed when the BIO is freed.BIO_set_fd() sets the socket of BIO bbbb to ffffdddd and the close
flag to cccclllloooosssseeee_ffffllllaaaagggg.
BIO_get_fd() places the socket in cccc if it is not NULL, it
also returns the socket. If cccc is not NULL it should be of type (int *).BIO_new_socket() returns a socket BIO using ssssoooocccckkkk and
cccclllloooosssseeee_ffffllllaaaagggg.
NNNNOOOOTTTTEEEESSSS 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 filedescriptors and use distinct I/O routines, Windows is one such platform. Any code mixing the two will not work on all platforms.
BIO_set_fd() and BIO_get_fd() are macros.

BIO_set_fd() always returns 1.

BIO_get_fd() returns the socket or -1 if the BIO has not
been initialized.BIO_new_socket() returns the newly allocated BIO or NULL is
an error occurred. SSSSEEEEEEEE AAAALLLLSSSSOOOO TBA19/Oct/2000 Last change: 0.9.8o 2
