.TH curl_mime_filedata 3 "22 August 2017" "libcurl 7.56.0" "libcurl Manual"
|
|
.SH NAME
|
|
curl_mime_filedata - set a mime part's body data from a file contents
|
|
.SH SYNOPSIS
|
|
.B #include <curl/curl.h>
|
|
.sp
|
|
.BI "CURLcode curl_mime_filedata(curl_mimepart * " part ,
|
|
.BI " const char * " filename ");"
|
|
.ad
|
|
.SH DESCRIPTION
|
|
\fIcurl_mime_filedata(3)\fP sets a mime part's body content from the named
|
|
file's contents. This is an alternative to \fIcurl_mime_data(3)\fP for setting
|
|
data to a mime part.
|
|
|
|
\fIpart\fP is the part's to assign contents to.
|
|
|
|
\fIfilename\fP points to the nul-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 \fIfilename\fP if it is a valid named file. This can be undone or
|
|
overridden by a subsequent call to \fIcurl_mime_filename(3)\fP.
|
|
|
|
The contents of the file is read during the file transfer in a streaming
|
|
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.
|
|
.SH AVAILABILITY
|
|
As long as at least one of HTTP, SMTP or IMAP is enabled. Added in 7.56.0.
|
|
.SH 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.
|
|
.SH EXAMPLE
|
|
.nf
|
|
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");
