53 which is used to pass an error code from IPsec policy manipulation library
56 can be used to obtain the error message string for the error code.
58 The array pointed to is not to be modified by the program.
63 as underlying function, calling
67 would make the return value from
69 invalid, or overwritten.
73 always return a pointer to C string.
74 The C string must not be overwritten by user programs.

81 first appeared in WIDE/KAME IPv6 protocol stack kit.
85 will return its result which may be overwritten by subsequent calls.
