CURLINFO_RTSP_CSEQ_RECV(3) Introduction to Library Functions

NAME

CURLINFO_RTSP_CSEQ_RECV - last received RTSP CSeq

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_RTSP_CSEQ_RECV, long *cseq);

DESCRIPTION

Pass a pointer to a long to receive the most recently received CSeq
from the server. If your application encounters a
CURLE_RTSP_CSEQ_ERROR then you may wish to troubleshoot and/or fix
the CSeq mismatch by peeking at this value.

PROTOCOLS

This functionality affects rtsp only

EXAMPLE

int main(void)
{
CURL *curl = curl_easy_init();
if(curl) {
CURLcode result;
curl_easy_setopt(curl, CURLOPT_URL, "rtsp://rtsp.example.com");
result = curl_easy_perform(curl);
if(result == CURLE_OK) {
long cseq;
curl_easy_getinfo(curl, CURLINFO_RTSP_CSEQ_RECV, &cseq);
}
curl_easy_cleanup(curl);
}
}

AVAILABILITY
