BIO_s_socket(3)              OpenSSL              BIO_s_socket(3)



NAME

       BIO_s_socket, BIO_new_socket - socket BIO


LIBRARY

       libcrypto, -lcrypto


SYNOPSIS

        #include <openssl/bio.h>

        BIO_METHOD *   BIO_s_socket(void);

        #define BIO_set_fd(b,fd,c)     BIO_int_ctrl(b,BIO_C_SET_FD,c,fd)
        #define BIO_get_fd(b,c)        BIO_ctrl(b,BIO_C_GET_FD,0,(char *)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 c.

       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.


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.
