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_errcodewhich 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
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 subsequent calls.
ipsec_errcode is not thread safe.
