CURLOPT_UPLOAD_FLAGS - Man Page

upload flags for IMAP

Synopsis

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_UPLOAD_FLAGS, long bitmask);

Description

Pass a long as parameter, which is set to a bitmask, to tell libcurl which flags to send the server relating to uploaded files. The currently supported flags are:

CURLULFLAG_ANSWERED: Sets the Answered flag for IMAP uploads. Indicates that the message has been replied to.
CURLULFLAG_DELETED: Sets the Deleted flag for IMAP uploads. Marks the message for deletion rather than immediately removing it.
CURLULFLAG_DRAFT: Sets the Draft flag for IMAP uploads. Marks the message as an uncompleted composition.
CURLULFLAG_FLAGGED: Sets the Flagged flag for IMAP uploads. Marks the message for special attention.
CURLULFLAG_SEEN: Sets the Seen flag for IMAP uploads. Marks the message as read.

Default

A bitmask with only the CURLULFLAG_SEEN flag set.

Protocols

This functionality affects imap and imaps

Example

static size_t read_cb(char *ptr, size_t size, size_t nmemb, void *userdata)
{
  FILE *src = userdata;
  /* copy as much data as possible into the 'ptr' buffer, but no more than
     'size' * 'nmemb' bytes */
  size_t retcode = fread(ptr, size, nmemb, src);

  return retcode;
}

int main(void)
{
  CURL *curl;
  FILE *src = fopen("local-file", "r");
  if(!src)
    return 1;

  curl = curl_easy_init();
  if(curl) {
    CURLcode result;
    curl_off_t fsize = 9876; /* set this to the size of the input file */

    /* we want to use our own read function */
    curl_easy_setopt(curl, CURLOPT_READFUNCTION, read_cb);

    /* enable uploading */
    curl_easy_setopt(curl, CURLOPT_UPLOAD, 1L);

    /* specify target */
    curl_easy_setopt(curl, CURLOPT_URL, "imap://example.com:993/mailbox");

    /* provide username */
    curl_easy_setopt(curl, CURLOPT_USERNAME, "user@example.com");

    /* provide password */
    curl_easy_setopt(curl, CURLOPT_PASSWORD, "password");

    /* specify that uploaded mail should be considered flagged */
    curl_easy_setopt(curl, CURLOPT_UPLOAD_FLAGS, CURLULFLAG_FLAGGED);

    /* now specify which pointer to pass to our callback */
    curl_easy_setopt(curl, CURLOPT_READDATA, src);

    /* Set the size of the file to upload */
    curl_easy_setopt(curl, CURLOPT_INFILESIZE_LARGE, (curl_off_t)fsize);

    /* perform the upload */
    result = curl_easy_perform(curl);
    curl_easy_cleanup(curl);
  }
  fclose(src);
