# NAME

curl_mime_addpart - append a new empty part to a mime structure

# SYNOPSIS

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

curl_mimepart *curl_mime_addpart(curl_mime *mime);
~~~

# DESCRIPTION

curl_mime_addpart(3) creates and appends a new empty part to the given

appended.

# EXAMPLE

~~~c
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);

    /* continue and set name + data to the part */
    curl_mime_data(part, "This is the field data", CURL_ZERO_TERMINATED);
    curl_mime_name(part, "data");
  }
}
~~~
