OpenDarwin 7.2.1 - man page for ipsec_strerror (opendarwin section 3)

IPSEC_STRERROR(3)		   BSD Library Functions Manual 		IPSEC_STRERROR(3)

NAME
     ipsec_strerror -- error message for IPsec policy manipulation library

SYNOPSIS
     #include <netinet6/ipsec.h>

     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 pro-
     gram.  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.
