curl_mime_data - 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.

CURLE_OK or a CURL error code upon failure.
