.TH curl_mime_data 3 "22 August 2017" "libcurl 7.56.0" "libcurl Manual"
.SH NAME
curl_mime_data - set a mime part's body data from memory
.SH SYNOPSIS
.nf
#include <curl/curl.h>

CURLcode curl_mime_data(curl_mimepart *part, const char *data,
                        size_t datasize);
.fi
.SH DESCRIPTION
\fIcurl_mime_data(3)\fP sets a mime part's body content from memory data.

\fIpart\fP is the mime part to assign contents to, created with
\fIcurl_mime_addpart(3)\fP.

\fIdata\fP points to the data that gets copied by this function. The storage
may safely be reused after the call.

\fIdatasize\fP is the number of bytes \fIdata\fP points to. It can be set to
\fICURL_ZERO_TERMINATED\fP to indicate \fIdata\fP is a null-terminated
character string.

Setting a part's contents multiple times is valid: only the value set by the
last call is retained. It is possible to unassign part's contents by setting
\fIdata\fP to NULL.

Setting large data is memory consuming: one might consider using
\fIcurl_mime_data_cb(3)\fP in such a case.
.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);

 /* add data to the part  */
 curl_mime_data(part, "raw contents to send", CURL_ZERO_TERMINATED);
.fi
.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.
