const char * ipsec_strerror
DESCRIPTION
netinet6/ipsec.h
declares
extern int ipsec_errcode;
which is used to pass an error code from IPsec policy manipulation library
to an user 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 program.
Since
ipsec_strerror
uses
strerror(3)
as underlying function, calling
strerror(3)
after
ipsec_strerror
would make the return value from
ipsec_strerror
invalid, or overwritten.
RETURN VALUES
ipsec_strerror
always return a pointer to C string.
The C string must not be overwritten by user programs.
SEE ALSO
ipsec_set_policy(3)
HISTORY
ipsec_strerror
first appeared in 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.
