BIO_s_socket(3) 19/Oct/2000 (0.9.7e) BIO_s_socket(3)
NAME
BIO_s_socket, BIO_new_socket - socket BIO
SYNOPSIS
#include <openssl/bio.h>
BIO_METHOD *BIO_s_socket(void);
long BIO_set_fd(BIO *b, int fd, long close_flag);
long BIO_get_fd(BIO *b, int *c);
BIO *BIO_new_socket(int sock, int close_flag);
DESCRIPTION
BIO_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 b to fd and the close
flag to close_flag.
BIO_get_fd() places the socket in c if it is not NULL, it
also returns the socket. If c is not NULL it should be of
type (int *).
BIO_new_socket() returns a socket BIO using sock and
close_flag.
NOTES
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_set_fd() and BIO_get_fd() are macros.
RETURN VALUES
BIO_s_socket() returns the socket BIO method.
BIO_set_fd() always returns 1.
BIO_get_fd() returns the socket or -1 if the BIO has not

BIO_new_socket() returns the newly allocated BIO or NULL is
