# Ns\_ConnDriverContext(3aolserver)

Routines to access communication driver data

```

```

## NAME

Ns\_ConnDriverContext, Ns\_ConnDriverName - Routines to access communication driver data

## SYNOPSIS

```
#include "ns.h"

void *
Ns_ConnDriverContext(conn)

char *
Ns_ConnDriverName(conn)
```

## ARGUMENTS

- Ns\_Conn *conn* (in)

  Pointer to open connection.

  ```

  ```

## DESCRIPTION

These functions provide access to the underyling communications driver data for an open connection.

- char \***Ns\_ConnDriverName**(*conn*)

  Returns the string name of the communication driver, e.g., "nssock". This is the name passed in the *Ns\_DriverInitData* structure in a call to **Ns\_DriverInit**, not the module name for the particular instance of the loaded driver.

- void \***Ns\_ConnDriverContent**(*conn*)

  Returns a pointer to the connection-specific driver context for the given connection.  This value is that of the *arg* element of the underlying *Ns\_Sock* structure allocated by the server and used by communication drivers to manage private state.  If the connection is closed, the value returned is always NULL.
