NAME

     ipsec_strerror — error messages for the IPsec policy manipulation library

LIBRARY

     IPsec Policy Control Library (libipsec, -lipsec)

SYNOPSIS

     #include <netinet6/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 subsequent calls.

     ipsec_errcode is not thread safe.
