The callback function will be +called by DTLS for every new DTLS packet that is sent. +.PP +The callback should return the timeout interval in micro seconds. +.PP +The \fItimer_us\fR parameter of the callback is the last set timeout +interval returned. On the first invocation of the callback, +this value will be 0. +.PP +At the beginning of the connection, if no timeout callback has been +set via \fBDTLS_set_timer_cb()\fR, the default timeout value is 1 second. +For all subsequent timeouts, the default behavior is to double the +duration up to a maximum of 1 minute. +.SH "RETURN VALUES" +.IX Header "RETURN VALUES" +Returns void. +.SH HISTORY +.IX Header "HISTORY" +The \fBDTLS_set_timer_cb()\fR function was added in OpenSSL 1.1.1. +.SH COPYRIGHT +.IX Header "COPYRIGHT" +Copyright 2017\-2025 The OpenSSL Project Authors.
