# dnet\_htoa(3)

DECnet address to host name translation

## NAME

dnet\_htoa - DECnet address to host name translation

## SYNOPSIS

**#include \<netdnet/dn.h\>**\
 **#include \<netdnet/dnetdb.h\>**\

**char \*dnet\_htoa (struct dn\_naddr \*addr)**

## DESCRIPTION

**dnet\_htoa** searches the decnet hosts file for  **addr** and returns the DECnet node name.\
 If no entry is found, returns the ascii DECnet address in the format **area.node** (1.1, 1.2, etc)

## EXAMPLE

```
#include <netdnet/dn.h>
#include <netdnet/dnetdb.h>
#include <sys/socket.h>
main(void)
{
    struct dn_naddr		binaddr;
    binaddr.a_len 	= 2;
    binaddr.a_addr[0] 	= 0x02;
    binaddr.a_addr[1] 	= 0x04;
    printf ("DECnet node name is %s",dnet_htoa(binaddr));
}
```
