This is mainly a convenience method to avoid needing to set a custom Transport: header for every SETUP request. The application must set a Transport: header before issuing a SETUP request. The application does not have to keep the string around after setting this option. .SH DEFAULT NULL .SH PROTOCOLS This functionality affects rtsp only .SH EXAMPLE .nf int main(void) { CURL *curl = curl_easy_init(); if(curl) { CURLcode res; curl_easy_setopt(curl, CURLOPT_URL, "rtsp://example.com/"); curl_easy_setopt(curl, CURLOPT_RTSP_REQUEST, CURL_RTSPREQ_SETUP); curl_easy_setopt(curl, CURLOPT_RTSP_TRANSPORT, "RTP/AVP;unicast;client_port=4588-4589"); res = curl_easy_perform(curl); curl_easy_cleanup(curl); } } .fi .SH AVAILABILITY Added in curl 7.20.0 .SH RETURN VALUE \fIcurl_easy_setopt(3)\fP returns a CURLcode indicating success or error.
