NAME
ipsec_strerror – error messages for the IPsec policy manipulation library
SYNOPSIS
#include <netipsec/ipsec.h>
const char *
ipsec_strerror();
DESCRIPTION
⟨netipsec/ipsec.h⟩ declares
extern int ipsec_errcode;
which is used to pass an error code from IPsec policy manipulation library to a user program. The ipsec_strerror() function 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 an underlying function, calling strerror(3) after ipsec_strerror() would overwrite the return value from ipsec_strerror() and make it invalid.
RETURN VALUES
The ipsec_strerror() function always returns a pointer to C string. The C string must not be overwritten by the caller.
SEE ALSO
HISTORY
The ipsec_strerror() function first appeared in WIDE/KAME IPv6 protocol stack kit.
BUGS
The ipsec_strerror() function will return its result which may be overwritten by subsequent calls.
ipsec_errcode is not thread safe.
