BIO_s_socket(3)BIO_s_socket(3)NAME
BIO_s_socket, BIO_new_socket - Socket BIO
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
The BIO_s_socket() function returns the socket BIO method. This is a
wrapper around 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 VALUESBIO_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 initialā
ized.
BIO_new_socket() returns the newly allocated BIO or NULL is an error
occurred.
