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