NAME

CURLINFO_RTSP_SERVER_CSEQ - get the next RTSP server CSeq

SYNOPSIS

#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.
