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

ipsec_strerror() can be used to obtain the error message string for the error code.

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 subsequent calls.

ipsec_errcode is not thread safe.
