.TH CURLOPT_RTSP_SESSION_ID 3 "19 Jun 2014" libcurl libcurl
.SH NAME
CURLOPT_RTSP_SESSION_ID \- RTSP session ID
.SH SYNOPSIS
.nf
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_RTSP_SESSION_ID, char *id);
.fi
.SH DESCRIPTION
Pass a char * as a parameter to set the value of the current RTSP Session ID
for the handle. Useful for resuming an in-progress session. Once this value is
set to any non-NULL value, libcurl returns \fICURLE_RTSP_SESSION_ERROR\fP if
ID received from the server does not match. If unset (or set to NULL), libcurl
automatically sets the ID the first time the server sets it in a response.
The application does not have to keep the string around after setting this
option.
