|
|
|
|
SSL_get_fd - get file descriptor linked to an SSL object
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/ssl.h>
|
|
|
|
int SSL_get_fd(SSL *ssl);
|
|
int SSL_get_rfd(SSL *ssl);
|
|
int SSL_get_wfd(SSL *ssl);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
SSL_get_fd() returns the file descriptor which is linked to B<ssl>.
|
|
SSL_get_rfd() and SSL_get_wfd() return the file descriptors for the
|
|
read or the write channel, which can be different. If the read and the
|
|
write channel are different, SSL_get_fd() will return the file descriptor
|
|
of the read channel.
|
|
|
|

The following return values can occur:
|
|
|

|
|
(suitable for file descriptors).

|
|
=item E<gt>=0
