NAME

if_freenameindex - free memory allocated by ifnameindex()

SYNOPSIS

#include <net/if.h>

void if_freenameindex(struct if_nameindex *ptr);

DESCRIPTION

Argument if_nameindex must be a pointer that was returned by if_nameindex(). Function if_freenameindex() frees the memory allocated by if_nameindex(). After if_freenameindex() has been called, the application should not use the array of which ptr is the address.

ERRORS

[EFAULT]

Argument if_nameindex is not a pointer that was returned by if_nameindex(). Note that implementations need not always detect this fault. If an implementation does not do so, the results are unspecified.
