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 declaresextern 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.
