netdir(3N) netdir(3N)

char c_uaddr; /* client’s universal addr */

char

m_uaddr; /* the result */

If s_uaddr is an address such as 0.0.0.0.1.12

, and the call is suc-

cessful,

m_uaddr is set to an address such as

192.11.109.89.1.12

. For most transports, m_uaddr

is identical

s_uaddr.

MULTITHREAD USAGE

Thread Safe: Yes

Cancel Safe: Yes

Fork Safe: No

Async-cancel Safe: No

Async-signal Safe: No

These functions can be called safely in a multithreaded environment. They may be cancellation points in

that they call functions that are cancel points.

In a multithreaded environment, these functions are not safe to be called by a child process after

fork()

and before exec(). These functions should not be called by a multithreaded application that supports

asynchronous cancellation or asynchronous signals.

RETURN VALUE

The netdir_perror() routine prints an error message on the standard output stating why one of the

name-to-address mapping routines failed. The error message is preceded by the string given as an argu-

ment.

The

netdir_sperror()

returns a pointer to a buffer which contains an error message string stating

why one of the name-to-address mapping routines failed. This buffer is overwritten on each call. In mul-

tithreaded applications, this buffer is implemented as thread-speciﬁc data.

The

netdir_getbyaddr()

function returns 0 on success and a non-zero value on failure.
