NAME

       curl_mime_filename - set a mime part's remote filename

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_mime_filename(curl_mimepart *part,
                                   const char *filename);

DESCRIPTION

       curl_mime_filename(3)  sets  a  mime  part's remote filename. When remote filename is set,
       content data is processed as a file, whatever is  the  part's  content  source.  A  part's
       remote  filename  is  transmitted  to  the  server  in  the associated Content-Disposition
       generated header.

       part is the part's handle to assign the remote filename to.

       filename points to the null-terminated filename string; it may be set to NULL to remove  a
       previously attached remote filename.

       The remote filename string is copied into the part, thus the associated storage may safely
       be released or reused after call. Setting a part's file name multiple times is valid: only
       the value set by the last call is retained.

PROTOCOLS

       This functionality affects http, imap and smtp

EXAMPLE

       static char imagebuf[]="imagedata";

       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);

           /* send image data from memory */
           curl_mime_data(part, imagebuf, sizeof(imagebuf));

           /* set a file name to make it look like a file upload */
           curl_mime_filename(part, "image.png");

           /* set name */
           curl_mime_name(part, "data");
         }
       }
