BIO_s_socket, BIO_new_socket - socket BIO
#include <openssl/bio.h>
const BIO_METHOD *BIO_s_socket(void);
BIO *BIO_new_socket(int sock, int close_flag);
BIO_s_socket() returns the socket BIO method. This is a wrapper round the
platform's socket routines.
BIO_read_ex() and
BIO_write_ex() 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_new_socket() returns a socket BIO using
sock and
close_flag.
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
platforms.
BIO_s_socket() returns the socket BIO method.
BIO_new_socket() returns the newly allocated BIO or NULL is an error
occurred.
