curl_mime_data - Man Page

set a mime part's body data from memory


#include <curl/curl.h>

CURLcode curl_mime_data(curl_mimepart *part, const char *data,
                        size_t datasize);


curl_mime_data(3) sets a mime part's body content from memory data.

data points to the data bytes: those are copied to the part and their storage may safely be reused after call. datasize is the number of data bytes: it can be set to CURL_ZERO_TERMINATED to indicate data is a null-terminated character string. part is the part's to assign contents to.

Setting a part's contents twice is valid: only the value set by the last call is retained. It is possible to unassign part's contents by setting data to NULL.

Setting large data is memory consuming: one might consider using curl_mime_data_cb(3) in such a case.


 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);


As long as at least one of HTTP, SMTP or IMAP is enabled. Added in 7.56.0.

Return Value

CURLE_OK or a CURL error code upon failure.
