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 filename is set, the mime type is taken from the filename extension, or application/octet-stream by default.
- For a multipart part, multipart/mixed.
- text/plain in other cases.
PROTOCOLS
This functionality affects http, imap and smtp
EXAMPLE
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"); } }
