NAME
BIO_s_socket,
BIO_new_socket —
socket BIO
SYNOPSIS
#include
<openssl/bio.h>
const BIO_METHOD *
BIO_s_socket(void);
BIO *
BIO_new_socket(int
sock, int close_flag);
DESCRIPTION
BIO_s_socket() returns the socket BIO method.
This is a wrapper around the platform's socket routines.
BIO_read(3) and
BIO_write(3) read
or write the underlying socket.
BIO_puts(3) is
supported but
BIO_gets(3) 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.
RETURN VALUES
BIO_s_socket() returns the socket BIO method.
BIO_new_socket() returns the newly allocated
BIO or NULL if an error occurred.
