16CURLOPT_RTSP_TRANSPORT - RTSP Transport: header
17
18# SYNOPSIS
19
20~~~c
21#include <curl/curl.h>
22
23CURLcode curl_easy_setopt(CURL *handle, CURLOPT_RTSP_TRANSPORT,
24                          char *transport);
25~~~
26
27# DESCRIPTION
28
29Pass a char pointer to tell libcurl what to pass for the Transport: header for
30this RTSP session. This is mainly a convenience method to avoid needing to set
31a custom Transport: header for every SETUP request. The application must set a
32Transport: header before issuing a SETUP request.
33
34The application does not have to keep the string around after setting this
35option.
