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 subsequent calls.
ipsec_errcode is not thread safe.
