5 SSL_waiting_for_async, SSL_get_async_wait_fd - manage asynchronous operations
9 #include <openssl/ssl.h>
11 int SSL_waiting_for_async(SSL *s);
12 int SSL_get_async_wait_fd(SSL *s);
16 SSL_waiting_for_async() determines whether an SSL connection is currently
17 waiting for asynchronous operations to complete (see the SSL_MODE_ASYNC mode in
18 L<SSL_CTX_set_mode(3)>).
20 SSL_get_async_wait_fd() returns a file descriptor which can be used in a call to
21 select() or poll() to determine whether the current asynchronous operation has
22 completed or not. A completed operation will result in data appearing as
23 available on the file descriptor (no actual data should be read from the file
24 descriptor). This function should only be called if the SSL object is currently
25 waiting for asynchronous work to complete (i.e. SSL_ERROR_WANT_ASYNC has been
26 received - see L<SSL_get_error(3)>).
30 SSL_waiting_for_async() will return 1 if the current SSL operation is waiting
31 for an async operation to complete and 0 otherwise.
33 SSL_get_async_wait_fd() will return a file descriptor that can be used in a call
34 to select() or poll() to wait for asynchronous work to complete, or -1 on error.
