# NAME
CURLINFO_SPEED_UPLOAD - get upload speed
# SYNOPSIS
~~~c
#include <curl/curl.h>
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_SPEED_UPLOAD, double *speed);
~~~
# DESCRIPTION
Pass a pointer to a double to receive the average upload speed that curl
measured for the complete upload. Measured in bytes/second.
CURLINFO_SPEED_UPLOAD_T(3) is a newer replacement that returns a more
sensible variable type.
# PROTOCOLS
# EXAMPLE
~~~c
int main(void)
{
CURL *curl = curl_easy_init();
if(curl) {
CURLcode res;
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
/* Perform the request */
res = curl_easy_perform(curl);
if(!res) {
double speed;
res = curl_easy_getinfo(curl, CURLINFO_SPEED_UPLOAD, &speed);
if(!res) {
printf("Upload speed %.0f bytes/sec\n", speed);
}
}
}
}
