curl_mime_data(3) libcurl Manual curl_mime_data(3)

NAME

curl_mime_data - set a mime part's body data from memory

SYNOPSIS

#include <curl/curl.h>
CURLcode curl_mime_data(curl_mimepart * part, const char * data , size_t datasize);

DESCRIPTION

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 nul-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.

AVAILABILITY

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.

EXAMPLE

 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);
