IPSEC_STRERROR(3)     DragonFly Library Functions Manual     IPSEC_STRERROR(3)

NAME

ipsec_strerror -- error message for 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 IPsec policy manipulation library to an user 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 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 sub- sequent calls. ipsec_errcode is not thread safe. DragonFly 3.9 May 6, 1998 DragonFly 3.9
