RELAY_SWITCH_SUBBUF(9)					      relay interface support					    RELAY_SWITCH_SUBBUF(9)

NAME

       relay_switch_subbuf - switch to a new sub-buffer

SYNOPSIS

       size_t relay_switch_subbuf(struct rchan_buf * buf, size_t length);

ARGUMENTS

       buf
	   channel buffer

       length
	   size of current event

DESCRIPTION

       Returns either the length passed in or 0 if full.

       Performs sub-buffer-switch tasks such as invoking callbacks, updating padding counts, waking up readers, etc.

NAME

       curl_formget - serialize a previously built multipart/formdata HTTP POST chain

SYNOPSIS

       #include <curl/curl.h>

       void curl_formget(struct curl_httppost *form, void *arg,  curl_formget_callback append);

DESCRIPTION

       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.

RETURN VALUE

       0 means everything was ok, non-zero means an error occurred

EXAMPLE

	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;
	}
