.TH CURLOPT_CHUNK_BGN_FUNCTION 3 "19 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
|
|
.SH NAME
|
|
CURLOPT_CHUNK_BGN_FUNCTION \- callback before a transfer with FTP wildcardmatch
|
|
.SH SYNOPSIS
|
|
.nf
|
|
#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);
|
|
.SH 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 \fItransfer_info\fP 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 \fICURLOPT_WILDCARDMATCH(3)\fP
|
|
option for now.
|
|
|
|
The target of transfer_info parameter is a "feature depended" structure. For
|
|
the FTP wildcard download, the target is curl_fileinfo structure (see
|
|
\fIcurl/curl.h\fP). The parameter \fIptr\fP is a pointer given by
|
|
\fICURLOPT_CHUNK_DATA(3)\fP. The parameter remains contains number of chunks
|
|
remaining per the transfer. If the feature is not available, the parameter has
|
|
zero value.
|
|
|
|
Return \fICURL_CHUNK_BGN_FUNC_OK\fP if everything is fine,
|
|
\fICURL_CHUNK_BGN_FUNC_SKIP\fP if you want to skip the concrete chunk or
|
|
\fICURL_CHUNK_BGN_FUNC_FAIL\fP to tell libcurl to stop if some error occurred.
