NAME
ipsec_strerror — error messages for the IPsec policy manipulation libraryDESCRIPTION
< 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

The ipsec_strerror() function will return its result which may be overwritten by subsequent calls.ipsec_errcode is not thread safe.
