NAME

       curl_mime_type - set a mime part's content type

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_mime_type(curl_mimepart * part, const char * mimetype);

DESCRIPTION

       curl_mime_type(3) sets a mime part's content type.

       part is the part's handle to assign the content type to.

       mimetype points to the nul-terminated file mime type string; it may be set to NULL to remove a previously
       attached mime type.

       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:
       - If set as a custom header, use this value.
       - application/form-data for an HTTP form post.
       -  If  a  remote  file  name  is  set,  the  mime  type  is  taken  from  the  file  name  extension,  or
       application/octet-stream by default.
       - For a multipart part, multipart/mixed.
       - text/plain in other cases.

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);

        /* 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");
