NAME

ipsec_strerror - error messages for the IPsec policy manipulation library

SYNOPSIS

In netinet6/ipsec.h Ft const char * Fn ipsec_strerror

DESCRIPTION

In 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 Fn 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 Fn ipsec_strerror uses strerror(3) as an underlying function, calling strerror(3) after Fn ipsec_strerror would overwrite the the return value from Fn ipsec_strerror and make it invalid.

RETURN VALUES

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

SEE ALSO

ipsec_set_policy3

HISTORY

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

BUGS

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

ipsec_errcode is not thread safe.
