## NAME

qb\_ipcs\_response\_send - Send a response to a incoming request.

## SYNOPSIS

```
#include <qb/qbipcs.h>

ssize_t qb_ipcs_response_send(
    qb_ipcs_connection_t   *c,     /* connection instance */
    const void             *data,  /* the message to send */
    size_t                  size   /* the size of the message */
);
```

## PARAMS

**c**    *connection instance*

**data** *the message to send*

**size** *the size of the message*

## DESCRIPTION

## RETURN VALUE

size sent or -errno for errors

## NOTE

the data must include a *qb\_ipc\_response\_header* at the top of the message. The client will read the size field to determine how much to recv.
