# NAME

CURLINFO_RTSP_SERVER_CSEQ - next RTSP server CSeq

# SYNOPSIS

~~~c
#include <curl/curl.h>

CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_RTSP_SERVER_CSEQ,
                           long *cseq);
~~~

# DESCRIPTION

Pass a pointer to a long to receive the next CSeq that is expected to be used
by the application.

Listening for server initiated requests is not implemented.

Applications wishing to resume an RTSP session on another connection should
retrieve this info before closing the active connection.

# EXAMPLE

~~~c
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_SERVER_CSEQ, &cseq);
    }
    curl_easy_cleanup(curl);
  }
}
