ipsec_strerror(3)

NAME

ipsec_strerror -- error messages for the IPsec policy manipulation library

#include <netinet6/ipsec.h>
const char *
ipsec_strerror();

<netinet6/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 the return value from ipsec_strerror() and make it invalid.

The ipsec_strerror() function always returns a pointer to C string. The C string must not be overwritten by the caller.

The ipsec_strerror() function first appeared in WIDE/KAME IPv6 protocol stack kit.

The ipsec_strerror() function will return its result which may be overwritten by subsequent calls.

ipsec_errcode is not thread safe.
