ipsec_strerror
—
error messages for the IPsec policy manipulation
library
IPsec Policy Control Library (libipsec, -lipsec)
#include
<netinet6/ipsec.h>
const char *
ipsec_strerror
(void);
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.
ipsec_strerror
() always returns a pointer
to a C string. The C string must not be overwritten by the calling
program.
ipsec_strerror
() first appeared in the
WIDE/KAME IPv6 protocol stack kit.
ipsec_strerror
() will return its result
which may be overwritten by subsequent calls.
ipsec_errcode is not thread safe.
