.TH curl_mime_filename 3 "December 04, 2023" "libcurl 8.5.0" "libcurl"

.SH NAME
curl_mime_filename - set a mime part's remote file name
.SH SYNOPSIS
.nf
#include <curl/curl.h>

CURLcode curl_mime_filename(curl_mimepart *part,
                            const char *filename);
.fi
.SH DESCRIPTION
\fIcurl_mime_filename(3)\fP 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.

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

\fIfilename\fP 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 multiple times is valid: only the value set by the last call is retained.
.SH EXAMPLE
.nf

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");
  }
}
.fi
