.TH gnurl_mime_type 3 "22 August 2017" "libcurl 7.56.0" "libgnurl Manual"
.SH NAME
curl_mime_type - set a mime part's content type
.SH SYNOPSIS
.B #include <gnurl/curl.h>
.sp
.BI "CURLcode curl_mime_type(curl_mimepart * " part ,
.BI "const char * " mimetype ");"
.ad
.SH DESCRIPTION
\fIcurl_mime_type(3)\fP sets a mime part's content type.
\fIpart\fP is the part's handle to assign the content type to.
\fImimetype\fP 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:
.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");
