curl_mime_free - free a previously built mime structure

Added in curl 7.56.0

curl_mime_free(3) is used to clean up data previously built/appended with curl_mime_addpart(3) and other mime-handling functions. This must be called when the data has been used, which typically means after curl_easy_perform(3) has been called. The handle to free is the one you passed to the CURLOPT_MIMEPOST(3) option: attached sub part mime structures must not be explicitly freed as they are by the top structure freeing. mime is the handle as returned from a previous call to curl_mime_init(3) and may be NULL. Passing in a NULL pointer in mime makes this function return immediately with no action.

int main(void) { CURL *curl = curl_easy_init(); if(curl) { /* Build the mime message. */ curl_mime *mime = curl_mime_init(curl); /* send off the transfer */ /* Free multipart message. */ curl_mime_free(mime); } }
