19# SYNOPSIS
20
21~~~c
22#include <curl/curl.h>
23
24CURLcode curl_easy_setopt(CURL *handle, CURLOPT_RTSP_TRANSPORT,
25                          char *transport);

28# DESCRIPTION
29
30Pass a char pointer to tell libcurl what to pass for the Transport: header for
31this RTSP session. This is mainly a convenience method to avoid needing to set
32a custom Transport: header for every SETUP request. The application must set a
33Transport: header before issuing a SETUP request.
34
35The application does not have to keep the string around after setting this
36option.
