SYNOPSIS

#include <netdb.h>

void freehostent(

struct hostent *ptr);

PARAMETERS

ptr Speciﬁes the host entity information structure (hostent) to be freed

DESCRIPTION

The freehostent() function frees a speciﬁed host entity information structure previously created

by the getipnodebyaddr() or getipnodebyname( ) function. Any dynamic storage pointed to by

the structure is also freed.

NOTES

Call this function once for each structure created by calls to getipnodebyaddr( ) or getipnode-

byname( ) before closing a socket.

RETURN VALUES

Upon successful completion, this function does not return a value. The address information

structure and associated storage have been returned to the system. Otherwise, an invalid address

reference causes application failure and results in a signal.

ERRORS

This function does not set errno.
