IPSEC_STRERROR(3) System Library Functions Manual IPSEC_STRERROR(3)
NAME
ipsec_strerror - error message for IPsec policy manipulation library
SYNOPSIS
#include <netinet6/ipsec.h>
const char *
ipsec_strerror();
DESCRIPTION
netinet6/ipsec.h declares
extern int ipsec_errcode;
which is used to pass an error code from IPsec policy manipulation
library to an user 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 program. Since
ipsec_strerror() uses strerror(3) as underlying function, calling
strerror(3) after ipsec_strerror() would make the return value from
ipsec_strerror() invalid, or overwritten.
RETURN VALUES
ipsec_strerror() always return a pointer to C string. The C string must
not be overwritten by user programs.
SEE ALSO
ipsec_set_policy(3)
HISTORY
ipsec_strerror() first appeared in 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.
