| 4 |
|
|---|
| 5 | SSL_get_fd, SSL_get_rfd, SSL_get_wfd - get file descriptor linked to an SSL object
|

| 7 | =head1 SYNOPSIS
|
|---|
| 8 |
|
|---|
| 9 | #include <openssl/ssl.h>
|
|---|
| 10 |
|
|---|
| 11 | int SSL_get_fd(const SSL *ssl);
|
|---|
| 12 | int SSL_get_rfd(const SSL *ssl);
|
|---|
| 13 | int SSL_get_wfd(const SSL *ssl);

|
|---|
| 15 | =head1 DESCRIPTION
|
|---|
| 16 |
|
|---|
| 17 | SSL_get_fd() returns the file descriptor which is linked to B<ssl>.
|
|---|
| 18 | SSL_get_rfd() and SSL_get_wfd() return the file descriptors for the
|
|---|
| 19 | read or the write channel, which can be different. If the read and the
|
|---|
| 20 | write channel are different, SSL_get_fd() will return the file descriptor
|
|---|
| 21 | of the read channel.
|
|---|
| 22 |
|
|---|
| 23 | =head1 RETURN VALUES
|
|---|
| 24 |
|
|---|
| 25 | The following return values can occur:
|
|---|
| 26 |
|
|---|
| 27 | =over 4
|
|---|
| 28 |
|
|---|
| 29 | =item -1
|
|---|
| 30 |
|
|---|
| 31 | The operation failed, because the underlying BIO is not of the correct type
|
|---|
| 32 | (suitable for file descriptors).
|
|---|
| 33 |
|
|---|
| 34 | =item E<gt>=0
|
|---|
| 35 |
|
|---|
| 36 | The file descriptor linked to B<ssl>.
