IPSEC_STRERROR(3) FreeBSD Library Functions Manual IPSEC_STRERROR(3)
NAME
ipsec_strerror - error messages for the IPsec policy manipulation library
SYNOPSIS
#include <netipsec/ipsec.h>
const char *
ipsec_strerror();
DESCRIPTION
<netipsec/ipsec.h> declares
extern int ipsec_errcode;
which is used to pass an error code from IPsec policy manipulation
library to a user program. The ipsec_strerror() function 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 an underlying function, calling
strerror(3) after ipsec_strerror() would overwrite the return value from
ipsec_strerror() and make it invalid.
RETURN VALUES
The ipsec_strerror() function always returns a pointer to C string. The
C string must not be overwritten by the caller.
SEE ALSO
ipsec_set_policy(3)
HISTORY
The ipsec_strerror() function first appeared in WIDE/KAME IPv6 protocol
stack kit.
BUGS
The ipsec_strerror() function will return its result which may be
overwritten by subsequent calls.
ipsec_errcode is not thread safe.
