# roar\_stream\_add\_data(3)

Adds data to a stream's input buffer using the control connection

## NAME

roar\_stream\_add\_data - Adds data to a stream's input buffer using the control connection

## SYNOPSIS

\#include \<roaraudio.h\>

int roar\_stream\_add\_data(struct roar\_connection \* con, struct roar\_stream \* s, char \* data, size\_t len);

## DESCRIPTION

This adds data to the input buffer of a stream. It's like doing some thing like this:

 write(stream\_fh, data, len);

but uses the control channel to add the data.

## PARAMETERS

- **con**

  The connection to the server.

- **s**

  The stream to add data to it's input buffer.

- **data**

  The data to add to the buffer.

- **len**

  The length of the data to be added.

## RETURN VALUE

On success these calls return 0.  On error, -1 is returned.

## EXAMPLES

FIXME

## BUGS

This call doesn't work with the current roard. The server does not use all of the buffer size and complains about unterruns.
