NAME
ipsec_strerror -- error messages for the IPsec policy manipulation library
LIBRARY
IPsec Policy Control Library (libipsec, -lipsec)
SYNOPSIS
#include <netipsec/ipsec.h> const char * 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. 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(3) as underlying function, calling strerror(3) 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(3)
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 sub- sequent calls. ipsec_errcode is not thread safe. NetBSD 8.0 January 4, 2012 NetBSD 8.0
