Some CURLOPT constants defined in the curl public headers were initially enums (= ints), or macros with bare numeric values. Recent curl releases upgraded them to `long` constants, to make them pass correctly to `curl_easy_setop()` by default, i.e. without requiring a `(long)` cast. This patch drops such casts from the examples embedded in the docs. At the same time it documents which curl release made them `long` types, to keep them useful when working with previous libcurl versions. Also: - drop a `(long)` cast that was never necessary. - CURLOPT_ALTSVC_CTRL.md: bump local copy of macros to long. - test1119: make it ignore symbols ending with an underscore, to skip wildcard, e.g. `**CURLAUTH_***`. Closes #18130

# NAME
|
|
|
|
CURLOPT_RTSP_TRANSPORT - RTSP Transport: header
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_RTSP_TRANSPORT,
|
|
char *transport);
|
|
~~~
|
|
|
|
# DESCRIPTION
|
|
|
|
Pass a char pointer to tell libcurl what to pass for the Transport: header for
|
|
this RTSP session. 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.

# EXAMPLE

|
~~~c

|
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);

# HISTORY
|
|
|
|
**CURL_RTSPREQ_*** enums became `long` types in 8.13.0, prior to this version
|
|
a `long` cast was necessary when passed to curl_easy_setopt(3).
|
|
|
|
# %AVAILABILITY%
|
|
|
|
# RETURN VALUE
|
|
|
|
curl_easy_setopt(3) returns a CURLcode indicating success or error.
|
|
|
|
CURLE_OK (0) means everything was OK, non-zero means an error occurred, see
|
|
libcurl-errors(3).
