CURLOPT_CHUNK_END_FUNCTION(3) Introduction to Library Functions

NAME

CURLOPT_CHUNK_END_FUNCTION - callback after a transfer with FTP
wildcard match

SYNOPSIS

#include <curl/curl.h>

long chunk_end_callback(void *ptr);

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_CHUNK_END_FUNCTION,
chunk_end_callback);

DESCRIPTION

Pass a pointer to your callback function, which should match the
prototype shown above.

This function gets called by libcurl as soon as a part of the stream
has been transferred (or skipped).

Return CURL_CHUNK_END_FUNC_OK if everything is fine or
CURL_CHUNK_END_FUNC_FAIL to tell the lib to stop if some error
occurred.

DEFAULT

NULL

PROTOCOLS

This functionality affects ftp only

EXAMPLE

#include <stdio.h>

struct callback_data {
FILE *output;
};

static long file_is_downloaded(struct callback_data *data)
{
if(data->output) {
fclose(data->output);
data->output = 0x0;
}
return CURL_CHUNK_END_FUNC_OK;
}

int main()
{
/* data for callback */
struct callback_data callback_info;

CURL *curl = curl_easy_init();

curl_easy_setopt(curl, CURLOPT_CHUNK_END_FUNCTION, file_is_downloaded);
curl_easy_setopt(curl, CURLOPT_CHUNK_DATA, &callback_info);
}

AVAILABILITY

Added in curl 7.21.0
