CURLOPT_READDATA(3)					     curl_easy_setopt options					       CURLOPT_READDATA(3)

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

       CURL *curl = curl_easy_init();
       struct MyData this;
       if(curl) {
	 curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");

	 /* pass pointer that gets passed in to the
	    CURLOPT_READFUNCTION callback */
	 curl_easy_setopt(curl, CURLOPT_READDATA, &this);

	 curl_easy_perform(curl);
       }

AVAILABILITY

       This option was once known by the older name CURLOPT_INFILE, the name CURLOPT_READDATA(3) was introduced in 7.9.7.

RETURN VALUE

       This will return CURLE_OK.
