=head1 NAME |
|
|
|
BIO_s_socket, BIO_new_socket - socket BIO |
|
|
|
=head1 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); |
|
|
|
=head1 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<b> to B<fd> and the close |
|
flag to B<close_flag>. |
|
|
|
BIO_get_fd() places the socket in B<c> if it is not NULL, it also |
|
returns the socket. If B<c> is not NULL it should be of type (int *). |
|
|
|
BIO_new_socket() returns a socket BIO using B<sock> and B<close_flag>. |
|
|
|
=head1 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. |
|
|
|
=head1 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. |
