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
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.
