# NAME
curl_mime_data - set a mime part's body data from memory
# SYNOPSIS
~~~c
#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.
*part* is the mime part to assign contents to, created with
curl_mime_addpart(3).
*data* points to the data that gets copied by this function. The storage
may safely be reused after the call.
*datasize* is the number of bytes *data* points to. It can be set to
*CURL_ZERO_TERMINATED* to indicate *data* is a null-terminated
character string.
Setting a part's contents multiple times 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.
# EXAMPLE
~~~c
int main(void)
{
curl_mime *mime;
curl_mimepart *part;
CURL *curl = curl_easy_init();
if(curl) {
/* 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);
}
}
