The API documentation for the MIME functions specify that the parts can be set twice, with the last call winning. While true, the user can set the parts n times for n > 2, reword to specify multiple API calls instead. Closes: #8860 Reviewed-by: Daniel Stenberg <daniel@haxx.se>

|
|
.SH NAME
|
|
curl_mime_subparts - set subparts of a multipart mime part
|
|
.SH SYNOPSIS
|
|
.nf
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_mime_subparts(curl_mimepart *part, curl_mime *subparts);
|
|
.fi
|
|
.SH DESCRIPTION
|
|
\fIcurl_mime_subparts(3)\fP sets a multipart mime part's content from a mime
|
|
structure.
|
|
|
|
\fIpart\fP is a handle to the multipart part.
|
|
|
|
\fIsubparts\fP is a mime structure handle holding the subparts. After
|
|
\fIcurl_mime_subparts\fP succeeds, the mime structure handle belongs to the
|
|
multipart part and must not be freed explicitly. It may however be updated by
|
|
subsequent calls to mime API functions.
|
|
|
|
Setting a part's contents multiple times is valid: only the value set by the
|
|
last call is retained. It is possible to unassign previous part's contents by
|
|
setting \fIsubparts\fP to NULL.
|
|
