ipsec_strerror(3) BSD Library Functions Manual ipsec_strerror(3)
NAME
ipsec_strerror -- error messages for the IPsec policy manipulation
library
LIBRARY
IPsec Policy Control Library (libipsec, -lipsec)
SYNOPSIS
#include <netinet6/ipsec.h>
const char *
ipsec_strerror(void);
DESCRIPTION
netinet6/ipsec.h declares
extern int ipsec_errcode;
which is used to pass an error code from the IPsec policy manipulation
library to a program. ipsec_strerror() can be used to obtain the error
message string for the error code.
The array pointed to is not to be modified by the calling program. Since
ipsec_strerror() uses strerror(3) as underlying function, calling
strerror(3) after ipsec_strerror() will make the return value from
ipsec_strerror() invalid or overwritten.
RETURN VALUES
ipsec_strerror() always returns a pointer to a C string. The C string
must not be overwritten by the calling program.
SEE ALSO
ipsec_set_policy(3)
HISTORY
ipsec_strerror() first appeared in the WIDE/KAME IPv6 protocol stack kit.
BUGS
ipsec_strerror() will return its result which may be overwritten by sub-
sequent calls.
ipsec_errcode is not thread safe.
