curl_mime_filedata(3) libcurl Manual curl_mime_filedata(3)
NAME
curl_mime_filedata - set a mime part's body data from a file contents
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_mime_filedata(curl_mimepart *part,
const char *filename);
DESCRIPTION
curl_mime_filedata(3) sets a mime part's body content from the named
file's contents. This is an alternative to curl_mime_data(3) for set-
ting data to a mime part.
part is the part's to assign contents to.
filename points to the null-terminated file's path name. The pointer
can be NULL to detach the previous part contents settings. Filename
storage can be safely be reused after this call.
As a side effect, the part's remote file name is set to the base name
of the given filename if it is a valid named file. This can be undone
or overridden by a subsequent call to curl_mime_filename(3).
The contents of the file is read during the file transfer in a stream-
ing manner to allow huge files to get transferred without using much
memory. It therefore requires that the file is kept intact during the
entire request.
If the file size cannot be determined before actually reading it (such
as for a device or named pipe), the whole mime structure containing the
part will be transferred as chunks by HTTP and rejected by IMAP.
Setting a part's contents twice is valid: only the value set by the
last call is retained.
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 data from this file */
curl_mime_filedata(part, "image.png");
/* set name */
curl_mime_name(part, "data");
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. CURLE_READ_ERROR is only an
indication that the file is not yet readable: it can be safely ignored
at this time, but the file must be made readable before the pertaining
easy handle is performed.
