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  null-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 multiple times 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.

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");

AVAILABILITY

       As long as at least one of HTTP, SMTP or IMAP is enabled. Added in 7.56.0.

       CURLE_OK or a CURL error code upon failure.
