# curl\_mime\_name(3)

set a mime part's name

## NAME

curl\_mime\_name - set a mime part's name

## SYNOPSIS

```
#include <curl/curl.h>
CURLcode curl_mime_name(curl_mimepart *part, const char *name);
```

## DESCRIPTION

*[curl\_mime\_name(3)](/curl_mime_name/3.md)* sets a mime part's name. This is the way HTTP form fields are named.

*part* is the part's handle to assign a name to.

*name* points to the null-terminated name string.

The name string is copied into the part, thus the associated storage may safely be released or reused after call. Setting a part's name multiple times is valid: only the value set by the last call is retained. It is possible to reset the name of a part by setting *name* to NULL.

## EXAMPLE

```
int main(void)
{
  curl_mime *mime;
  curl_mimepart *part;
  CURL *curl = curl_easy_init();
  if(curl) {
    /* create a mime handle */
    mime = curl_mime_init(curl);
    /* add a part */
    part = curl_mime_addpart(mime);
    /* give the part a name */
    curl_mime_name(part, "shoe_size");
  }
}
```

## AVAILABILITY

As long as at least one of HTTP, SMTP or IMAP is enabled. Added in 7.56.0.

## RETURN VALUE

CURLE\_OK or a CURL error code upon failure.
