11 CURLcode curl_mime_filedata(curl_mimepart * part, const char * file‐
12 name);
13
15 curl_mime_filedata(3) sets a mime part's body content from the named
16 file's contents. This is an alternative to curl_mime_data(3) for set‐
17 ting data to a mime part.
18
19 part is the part's to assign contents to.
20
21 filename points to the nul-terminated file's path name. The pointer can
22 be NULL to detach the previous part contents settings. Filename stor‐
23 age can be safely be reused after this call.
24
25 As a side effect, the part's remote file name is set to the base name
26 of the given filename if it is a valid named file. This can be undone
27 or overridden by a subsequent call to curl_mime_filename(3).
28
29 The contents of the file is read during the file transfer in a stream‐
30 ing manner to allow huge files to get transferred without using much
31 memory. It therefore requires that the file is kept intact during the
32 entire request.
33
34 If the file size cannot be determined before actually reading it (such
35 as for a device or named pipe), the whole mime structure containing the
36 part will be transferred as chunks by HTTP and rejected by IMAP.
37
38 Setting a part's contents twice is valid: only the value set by the
39 last call is retained.
40
42 As long as at least one of HTTP, SMTP or IMAP is enabled. Added in
43 7.56.0.
44
46 CURLE_OK or a CURL error code upon failure. CURLE_READ_ERROR is only an
47 indication that the file is not yet readable: it can be safely ignored
48 at this time, but the file must be made readable before the pertaining
49 easy handle is performed.
