CURLOPT_WRITEDATA(3)

CURLOPT_WRITEDATA(3)       curl_easy_setopt options       CURLOPT_WRITEDATA(3)



NAME
       CURLOPT_WRITEDATA - pointer passed to the write callback

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_WRITEDATA, void *pointer);

DESCRIPTION
       A  data  pointer  to  pass  to  the write callback. If you use the CUR‐
       LOPT_WRITEFUNCTION(3) option, this is the pointer you will get in  that
       callback's  fourth  and  last argument. If you do not use a write call‐
       back, you must make pointer a 'FILE *' (cast to 'void  *')  as  libcurl
       will pass this to fwrite(3) when writing data.

       The internal CURLOPT_WRITEFUNCTION(3) will write the data to the FILE *
       given with this option, or to stdout if this option has not been set.

       If you are using libcurl as a win32 DLL, you MUST use a  CURLOPT_WRITE‐
       FUNCTION(3) if you set this option or you will experience crashes.

DEFAULT
       By default, this is a FILE * to stdout.

PROTOCOLS
       Used for all protocols.

EXAMPLE
       A  common  technique is to use the write callback to store the incoming
       data into a dynamically growing allocated buffer, and  then  this  CUR‐
       LOPT_WRITEDATA(3)  is  used to point to a struct or the buffer to store
       data      in.      Like      in      the      getinmemory      example:
       https://curl.se/libcurl/c/getinmemory.html

AVAILABILITY
       Available  in  all  libcurl versions. This option was formerly known as
       CURLOPT_FILE, the name CURLOPT_WRITEDATA(3) was introduced in 7.9.7.

RETURN VALUE
       This will return CURLE_OK.
