+.SH DESCRIPTION
+.IX Header "DESCRIPTION"
+\&\fBBIO_socket_wait()\fR waits on the socket \fBfd\fR for reading if \fBfor_read\fR is not 0,
+else for writing, at most until \fBmax_time\fR.
+It succeeds immediately if \fBmax_time\fR == 0 (which means no timeout given).
+.PP
+\&\fBBIO_wait()\fR waits at most until \fBmax_time\fR on the given (typically socket-based)
+\&\fBbio\fR, for reading if \fBbio\fR is supposed to read, else for writing.
+It is used by \fBBIO_do_connect_retry()\fR and can be used together \fBBIO_read\fR\|(3).
+It succeeds immediately if \fBmax_time\fR == 0 (which means no timeout given).
+If sockets are not available it supports polling by succeeding after sleeping
+at most the given \fBnap_milliseconds\fR in order to avoid a tight busy loop.
+Via \fBnap_milliseconds\fR the caller determines the polling granularity.
+.PP
+\&\fBBIO_do_connect_retry()\fR connects via the given \fBbio\fR.
+It retries \fBBIO_do_connect()\fR as far as needed to reach a definite outcome,
+i.e., connection succeeded, timeout has been reached, or an error occurred.
+For nonblocking and potentially even non-socket BIOs it polls
+every \fBnap_milliseconds\fR and sleeps in between using \fBBIO_wait()\fR.
+If \fBnap_milliseconds\fR is < 0 then a default value of 100 ms is used.
+If the \fBtimeout\fR parameter is > 0 this indicates the maximum number of seconds
+to wait until the connection is established or a definite error occurred.
+A value of 0 enables waiting indefinitely (i.e, no timeout),
+while a value < 0 means that \fBBIO_do_connect()\fR is tried only once.
+The function may, directly or indirectly, invoke \fBERR_clear_error()\fR.
+.SH "RETURN VALUES"
+.IX Header "RETURN VALUES"
+\&\fBBIO_socket_wait()\fR, \fBBIO_wait()\fR, and \fBBIO_do_connect_retry()\fR
+return \-1 on error, 0 on timeout, and 1 on success.
