SYNOPSIS

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

DESCRIPTION

netinet6/ipsec.h declares

extern int ipsec_errcode

which is used to pass an error code from the IPsec policy manipulation library to a program. Fn ipsec_strerror can be used to obtain the error message string for the error code.

The array pointed to is not to be modified by the calling program. Since Fn ipsec_strerror uses strerror(3) as underlying function, calling strerror(3) after Fn ipsec_strerror will make the return value from Fn ipsec_strerror invalid or overwritten.

RETURN VALUES

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

HISTORY

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