CURLINFO_RTSP_SERVER_CSEQ(3) Introduction to Library Functions

NAME

CURLINFO_RTSP_SERVER_CSEQ - 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.

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.

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

AVAILABILITY
