# [NAME](#NAME)

CURLOPT\_PUT - make an HTTP PUT request

# [SYNOPSIS](#SYNOPSIS)

```
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PUT, long put);
```

# [DESCRIPTION](#DESCRIPTION)

A parameter set to 1 tells the library to use HTTP PUT to transfer data. The data should be set with [*CURLOPT\_READDATA(3)*](/man/os/curl/CURLOPT_READDATA.3) and [*CURLOPT\_INFILESIZE(3)*](/man/os/curl/CURLOPT_INFILESIZE.3).

This option is **deprecated** since version 7.12.1. Use [*CURLOPT\_UPLOAD(3)*](/man/os/curl/CURLOPT_UPLOAD.3).

# [DEFAULT](#DEFAULT)

This functionality affects http only

```
static size_t read_cb(char *ptr, size_t size, size_t nmemb, void *userdata)
{


  FILE *src = userdata;


  /* copy as much data as possible into the 'ptr' buffer, but no more than


     'size' * 'nmemb' bytes */


  size_t retcode = fread(ptr, size, nmemb, src);


  return retcode;
}
int main(void)
{


  CURL *curl;


  FILE *src = fopen("local-file", "r");


  if(!src)


    return 1;


  curl = curl_easy_init();


  if(curl) {


    CURLcode result;


    curl_off_t fsize = 123456; /* set this to the size of the input file */


    /* we want to use our own read function */


    curl_easy_setopt(curl, CURLOPT_READFUNCTION, read_cb);


    /* enable PUT */


    curl_easy_setopt(curl, CURLOPT_PUT, 1L);


    /* specify target */


    curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/dir/to/newfile");


    /* now specify which pointer to pass to our callback */


    curl_easy_setopt(curl, CURLOPT_READDATA, src);


    /* Set the size of the file to upload */


    curl_easy_setopt(curl, CURLOPT_INFILESIZE_LARGE, (curl_off_t)fsize);


    /* Now run off and do what you have been told */


    result = curl_easy_perform(curl);


    curl_easy_cleanup(curl);


  }


  fclose(src);
}
