Error messages for IPsec policy manipulation library
#include <netinet6/ipsec.h> const char *ipsec_strerror( void );
libipsec
Use the -l ipsec option to qcc to link against this library.
The ipsec_strerror() function obtains the error message for the last IPsec call that failed. If you program includes the declaration:
extern int ipsec_errcode;
you can access the error code from the IPsec policy manipulation library. You can use ipsec_strerror() to obtain the error message corresponding to the error code.
A pointer to a C string.
Don't modify the string that this function returns. Since ipsec_strerror() uses strerror() as its underlying function, calling strerror() after calling ipsec_strerror() overwites or invalidates the return value from ipsec_strerror(). |
See the example of ipsec_set_policy().
