.TH CURLOPT_READDATA 3 "16 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
|
|
.SH NAME
|
|
CURLOPT_READDATA \- custom pointer passed to the read callback
|
|
.SH SYNOPSIS
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_READDATA, void *pointer);
|
|
.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'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
|
|
\fICURLOPT_READFUNCTION(3)\fP if you set this option.
|
|
.SH DEFAULT
|
|
By default, this is a FILE * to stdin.
|
|
.SH PROTOCOLS
|
|
This is used for all protocols when sending data.
|
|
.SH EXAMPLE
|
|
.nf
|
|
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);
|
|
}
|
|
.fi
|
|
.SH AVAILABILITY
|
|
This option was once known by the older name CURLOPT_INFILE, the name
|
|
\fICURLOPT_READDATA(3)\fP was introduced in 7.9.7.
|
|
.SH RETURN VALUE

|
This will return CURLE_OK.
|
|
