curl_formget(3) |

curl_formget - serialize a previously build multipart/formdata HTTP POST chain
#include <curl/curl.h>
void curl_formget(struct curl_httppost *form, void *arg, curl_formget_callback append);
curl_formget() is used to serialize data previously built/appended with curl_formadd(3). Accepts a void pointer as second argument which will be passed to the curl_formget_callback function.
typedef size_t (*curl_formget_callback)(void *arg, const char *buf, size_t len);
The
curl_formget_callback will be executed for each part of the
HTTP POST
chain. The void *arg pointer will be the one passed as
second argument to
curl_formget(). The character buffer passed to it must not
be freed. The
callback should return the buffer length passed to it on
success.
0 means everything was ok, non-zero means an error occurred
size_t
print_httppost_callback(void *arg, const char *buf, size_t
len)
{
fwrite(buf, len, 1, stdout);
(*(size_t *) arg) += len;
return len;
}
size_t print_httppost(struct curl_httppost *post)
{
size_t total_size = 0;
if(curl_formget(post, &total_size,
print_httppost_callback)) {
return (size_t) -1;
}
return total_size;
}
