CURLOPT_READDATA(3) curl_easy_setopt options CURLOPT_READDATA(3) NAME CURLOPT_READDATA - 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 CUR- LOPT_READFUNCTION(3) option, this is the pointer you will get as input in the 4th argument to the callback. If you do not 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 are using libcurl as a win32 DLL, you MUST use a CURLOPT_READ- FUNCTION(3) if you set this option or you will experience crashes. 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, "https://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.
