## NAME

CURLINFO\_SIZE\_UPLOAD - number of uploaded bytes

## SYNOPSIS

```
#include <curl/curl.h>
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_SIZE_UPLOAD,
                           double *uploadp);
```

## DESCRIPTION

  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode result;
    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
    /* Perform the request */
    result = curl_easy_perform(curl);
    if(result == CURLE_OK) {
      double ul;
      result = curl_easy_getinfo(curl, CURLINFO_SIZE_UPLOAD, &ul);
      if(result == CURLE_OK) {
        printf("Uploaded %.0f bytes\n", ul);
      }
    }
  }
}
```
