BIO_s_socket(3)             OpenSSL             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
       been initialized.

       BIO_new_socket() returns the newly allocated BIO or NULL
       is an error occurred.
