+.TH CURLOPT_WRITEDATA 3 "16 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
+.SH NAME
+CURLOPT_WRITEDATA \- custom pointer passed to the write callback
+.SH SYNOPSIS
+#include <curl/curl.h>
+
+CURLcode curl_easy_setopt(CURL *handle, CURLOPT_WRITEDATA, void *pointer);
+.SH DESCRIPTION
+A data \fIpointer\fP to pass to the write callback. If you use the
+\fICURLOPT_WRITEFUNCTION(3)\fP option, this is the pointer you'll get in that
+callback's 4th argument. If you don't use a write callback, you must make
+\fIpointer\fP a 'FILE *' (cast to 'void *') as libcurl will pass this to
+\fIfwrite(3)\fP when writing data.
+
+The internal \fICURLOPT_WRITEFUNCTION(3)\fP will write the data to the FILE *
+given with this option, or to stdout if this option hasn't been set.
+
+If you're using libcurl as a win32 DLL, you \fBMUST\fP use a
+\fICURLOPT_WRITEFUNCTION(3)\fP if you set this option or you will experience
+crashes.
+.SH DEFAULT
+By default, this is a FILE * to stdout.
+.SH PROTOCOLS
+Used for all protocols.
+.SH EXAMPLE
+A common technique is to use the write callback to store the incoming data
+into a dynamically growing allocated buffer, and then this
+\fICURLOPT_WRITEDATA(3)\fP is used to point to a struct or the buffer to store
+data in. Like in the getinmemory example:
+https://curl.haxx.se/libcurl/c/getinmemory.html
+.SH AVAILABILITY
+Available in all libcurl versions. This option was formerly known as
+\fICURLOPT_FILE\fP, the name \fICURLOPT_WRITEDATA(3)\fP was introduced in
+7.9.7.
+.SH RETURN VALUE
+This will return CURLE_OK.
