# NAME
|
|
|
|
curl_mime_type - set a mime part's content type
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#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 filename 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
|
|
|
|
~~~c
|
|
int main(void)
|
|
{
|
|
curl_mime *mime;
|
|
curl_mimepart *part;
|
|
|
|
CURL *curl = curl_easy_init();
|
|
if(curl) {
|
|
/* create a mime handle */
|
|
mime = curl_mime_init(curl);
|
|
|
|
/* 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");
