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

     26 CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_SPEED_DOWNLOAD,

     30 # DESCRIPTION
     31 
     32 Pass a pointer to a double to receive the average download speed that curl
     33 measured for the complete download. Measured in bytes/second.
     34 
     35 CURLINFO_SPEED_DOWNLOAD_T(3) is a newer replacement that returns a more
     36 sensible variable type.
