NAME
CURLOPT_CHUNK_BGN_FUNCTION - callback before a transfer with FTP wildcardmatch
SYNOPSIS
#include <curl/curl.h> long chunk_bgn_callback(const void *transfer_info, void *ptr, int remains); CURLcode curl_easy_setopt(CURL *handle, CURLOPT_CHUNK_BGN_FUNCTION, chunk_bgn_callback);
DESCRIPTION
Pass a pointer to your callback function, which should match the prototype shown above. This callback function gets called by libcurl before a part of the stream is going to be transferred (if the transfer supports chunks). The transfer_info pointer will point to a struct curl_fileinfo with details about the file that is about to get transferred. This callback makes sense only when using the CURLOPT_WILDCARDMATCH(3) option for now. The target of transfer_info parameter is a "feature depended" structure. For the FTP wildcard download, the target is curl_fileinfo struc- ture (see curl/curl.h). The parameter ptr is a pointer given by CURLOPT_CHUNK_DATA(3). The parameter remains contains number of chunks remaining per the transfer. If the feature is not available, the parameter has zero value. Return CURL_CHUNK_BGN_FUNC_OK if everything is fine, CURL_CHUNK_BGN_FUNC_SKIP if you want to skip the concrete chunk or CURL_CHUNK_BGN_FUNC_FAIL to tell libcurl to stop if some error occurred.
