The mime type string is copied into the part, thus the associated storage may safely be released or reused after call. Setting a part's type twice is valid: only the value set by the last call is retained. In the absence of a mime type and if needed by the protocol specifications, a default mime type is determined by the context: .br - If set as a custom header, use this value. .br - application/form-data for an HTTP form post. .br - If a remote file name is set, the mime type is taken from the file name extension, or application/octet-stream by default. .br - For a multipart part, multipart/mixed. .br - text/plain in other cases. .SH AVAILABILITY As long as at least one of HTTP, SMTP or IMAP is enabled. Added in 7.56.0. .SH RETURN VALUE CURLE_OK or a CURL error code upon failure. .SH EXAMPLE .nf curl_mime *mime; curl_mimepart *part; /* create a mime handle */ mime = curl_mime_init(easy); /* add a part */ part = curl_mime_addpart(mime); /* get data from this file */ curl_mime_filedata(part, "image.png"); /* content-type for this part */ curl_mime_type(part, "image/png"); /* set name */ curl_mime_name(part, "image"); .fi .SH "SEE ALSO" .BR curl_mime_addpart "(3)," .BR curl_mime_name "(3)," .BR curl_mime_data "(3)"
