.TH CURLOPT_READDATA 3 "2024-06-01" libcurl
.SH NAME
CURLOPT_READDATA \- pointer passed to the read callback
.SH SYNOPSIS
.nf
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_READDATA, void *pointer);
.fi
.SH DESCRIPTION
Data \fIpointer\fP to pass to the file read function. If you use the
\fICURLOPT_READFUNCTION(3)\fP option, this is the pointer you get as input in
the fourth 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 \(aqvoid *\(aq).
If you are using libcurl as a DLL on Windows, you must use the
\fICURLOPT_READFUNCTION(3)\fP callback if you set this option, otherwise you
might experience crashes.
.SH DEFAULT
By default, this is a FILE * to stdin.

/* pass pointer that gets passed in to the
CURLOPT_READFUNCTION callback */
curl_easy_setopt(curl, CURLOPT_READDATA, &this);
curl_easy_perform(curl);
}
}
.fi
.SH AVAILABILITY

\fICURLOPT_READDATA(3)\fP was introduced in 7.9.7.
