NAME

     ipsec_strerror - error code for IPsec policy manipulation library


LIBRARY

     IPsec Policy Control Library (libipsec, -lipsec)


SYNOPSIS

     #include <netinet6/ipsec.h>

     const char *
     ipsec_strerror();


DESCRIPTION

     netinet6/ipsec.h declares

           extern int ipsec_errcode;

     which is used to pass error code from IPsec policy manipulation library
     to user program.  ipsec_strerror() can be used to obtain 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
