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 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.

/* get data
from this file */
curl_mime_filedata(part, "image.png");
/* content-type

curl_mime_type(part, "image/png");
/* set name */
curl_mime_name(part, "image");
