man ipsec_strerror (Fonctions bibliothèques) - ipsec_strerror
NAME
ipsec_strerror - error messages for the IPsec policy manipulation library
LIBRARY
SYNOPSIS
ipsec_strerror void
DESCRIPTION
netinet6/ipsec.h
declares
which is used to pass an error code from the IPsec policy manipulation library to a program. 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 ipsec_strerror uses strerror() as underlying function, calling strerror() after ipsec_strerror will make the return value from ipsec_strerror invalid or overwritten.
RETURN VALUES
ipsec_strerror
always returns a pointer to a C string. The C string must not be overwritten by the calling program.
SEE ALSO
ipsec_set_policy()
HISTORY
ipsec_strerror
first appeared in the WIDE/KAME IPv6 protocol stack kit.
BUGS
ipsec_strerror
will return its result which may be overwritten by subsequent calls.
ipsec_errcode is not thread safe.
