curl_mime_filename - set a mime part remote file name


curl_mime_filename - set a mime part's remote filename


#include <curl/curl.h>
CURLcode curl_mime_filename(curl_mimepart *part,
                            const char *filename);


curl_mime_filename 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.
