NAME

curl_mime_filename - set a mime part's remote file name

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 file name. When remote file name is set, content data is processed as a file, whatever is the part's content source. A part's remote file name is transmitted to the server in the associated Content-Disposition generated header.

part is the part's handle to assign the remote file name to.

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

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

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.

EXAMPLE

 curl_mime *mime;
 curl_mimepart *part;

 /* create a mime handle */
 mime = curl_mime_init(easy);

 /* add a part */
 part = curl_mime_addpart(mime);

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

 /* 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");
