+ * (c->master != NULL) is true and pipes are supported.
+ * To be used in Apache modules implementing WebSockets in Apache httpd
+ * versions that do not support the corresponding `ap_get_pollfd_from_conn()`
+ * function.
+ * When available, use `ap_get_pollfd_from_conn()` instead of this function.
+ *
+ * How it works: pass in a `apr_pollfd_t` which gets populated for
+ * monitoring the input of connection `c`. If `c` is not a HTTP/2
+ * stream connection, the function will return `APR_ENOTIMPL`.
+ * `ptimeout` is optional and, if passed, will get the timeout in effect
+ *
+ * On platforms without support for pipes (e.g. Windows), this function
+ * will return `APR_ENOTIMPL`.
