=head1 NAME |
|
|
|
SSL_get_fd - get file descriptor linked to an SSL object |
|
|
|
=head1 SYNOPSIS |
|
|
|
#include <openssl/ssl.h> |
|
|
|
int SSL_get_fd(const SSL *ssl); |
|
int SSL_get_rfd(const SSL *ssl); |
|
int SSL_get_wfd(const 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. |
|
|
|
=head1 RETURN VALUES |

|
The following return values can occur: |
|
|
|
=over 4 |

|
(suitable for file descriptors). |
