NAME

ipsec_strerror

 - error messages for the IPsec policy manipulation library

SYNOPSIS

#include <netipsec/ipsec.h>
const char * ipsec_strerror ();

DESCRIPTION

#include <netipsec/ipsec.h>
declares

extern int ipsec_errcode;

which is used to pass an error code from IPsec policy manipulation library to a user program. The ipsec_strerror ();
function can be used to obtain the error message string for the error code.

The array pointed to is not to be modified by the program. Since ipsec_strerror ();
uses strerror(3) as an underlying function, calling strerror(3) after ipsec_strerror ();
would overwrite the the return value from ipsec_strerror ();
and make it invalid.
