.SH NAME
curl_mime_data \- set a mime part\(aqs 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\(aqs 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\(aqs contents multiple times is valid: only the value set by the
last call is retained. It is possible to unassign part\(aqs 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 PROTOCOLS
This functionality affects http, imap and smtp
.SH EXAMPLE

    /* create a mime handle */
    mime = curl_mime_init(curl);

    /* add a part */
    part = curl_mime_addpart(mime);

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