NAME¶
CURLOPT_READDATA - custom pointer passed to the read callback
SYNOPSIS¶
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_READDATA, void *pointer);
DESCRIPTION¶
Data
pointer to pass to the file read function. If you use the
CURLOPT_READFUNCTION(3) option, this is the pointer you'll get as input
in the 4th argument to the callback.
If you don't specify a read callback but instead rely on the default internal
read function, this data must be a valid readable FILE * (cast to 'void *').
If you're using libcurl as a win32 DLL, you MUST use a
CURLOPT_READFUNCTION(3) if you set this option.
DEFAULT¶
By default, this is a FILE * to stdin.
PROTOCOLS¶
This is used for all protocols when sending data.
EXAMPLE¶
TODO
AVAILABILITY¶
