NAME¶
CURLOPT_UPLOAD_FLAGS - 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);
}
