# ACE\_UNIX\_Addr(3)

Defines the \`\`UNIX domain address family'' address format.

## NAME

ACE\_UNIX\_Addr -  Defines the \`\`UNIX domain address family'' address format.

## SYNOPSIS

```
#include <ace/UNIX_Addr.h>
class ACE_UNIX_Addr : public ACE_Addr
{
  public:
    ACE_UNIX_Addr (void);
    ACE_UNIX_Addr (const ACE_UNIX_Addr &sa);
    ACE_UNIX_Addr (const char rendezvous_point[]);
    ACE_UNIX_Addr (const sockaddr_un *, int len);
    int set (const ACE_UNIX_Addr &sa);
    int set (const char rendezvous_point[]);
    int set (const sockaddr_un *, int len);
    virtual void *get_addr (void) const;
    virtual void set_addr (void *addr, int len);
    virtual int addr_to_string (char addr[], size_t) const;
    virtual int string_to_addr (const char addr[]);
    int operator == (const ACE_UNIX_Addr &SAP) const;
    int operator != (const ACE_UNIX_Addr &SAP) const;
    const char *get_path_name (void) const;
    virtual u_long hash (void) const;
    void dump (void) const;
    ACE_ALLOC_HOOK_DECLARE;
  private:
    sockaddr_un unix_addr_;
