CURLOPT\_CURLU(3) Library Functions Manual CURLOPT\_CURLU(3)

# [NAME](#NAME)

CURLOPT\_CURLU - URL in URL handle format

# [SYNOPSIS](#SYNOPSIS)

```
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_CURLU, CURLU *pointer);
```

# [DESCRIPTION](#DESCRIPTION)

Pass in a pointer to the *URL* handle to work with. The parameter should be a *CURLU pointer*. Setting [*CURLOPT\_CURLU(3)*](/man/os/curl/CURLOPT_CURLU.3) explicitly overrides [*CURLOPT\_URL(3)*](/man/os/curl/CURLOPT_URL.3).

[*CURLOPT\_URL(3)*](/man/os/curl/CURLOPT_URL.3) or [*CURLOPT\_CURLU(3)*](/man/os/curl/CURLOPT_CURLU.3) **must** be set before a transfer is started.

libcurl uses this handle and its contents read-only and does not change its contents. An application can update the contents of the URL handle after a transfer is done and if the same handle is used in a subsequent request the updated contents is used.

# [PROTOCOLS](#PROTOCOLS)

This functionality affects all supported protocols

# [EXAMPLE](#EXAMPLE)

```
int main(void)
{


  CURL *curl = curl_easy_init();


  CURLU *urlp = curl_url();


  if(curl) {


    CURLcode result;


    CURLUcode ret;


    ret = curl_url_set(urlp, CURLUPART_URL, "https://example.com", 0);


    curl_easy_setopt(curl, CURLOPT_CURLU, urlp);


    result = curl_easy_perform(curl);


    curl_url_cleanup(urlp);


    curl_easy_cleanup(curl);


  }
}
```
