NAMEBIO_s_socket, BIO_new_socket - socket BIO
#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);
DESCRIPTIONBIO_s_socket() returns the socket
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_set_fd() sets the socket of
BIO_get_fd() places the socket in c if it is not
BIO_new_socket() returns a socket
NOTESSocket 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 VALUESBIO_s_socket() returns the socket
BIO_set_fd() always returns 1.
BIO_get_fd() returns the socket or -1 if the
BIO_new_socket() returns the newly allocated
