struct tm* ldns_serial_arithmitics_gmtime_r | ( | int32_t | time, | |

struct tm * | result | |||
) |
The function interprets time as the number of seconds since epoch with respect to now using serial arithmitics (rfc1982).
That number of seconds is then converted to broken-out time information. This is especially usefull when converting the inception and expiration fields of RRSIG records.
[in] | time | number of seconds since epoch (midnight, January 1st, 1970) to be intepreted as a serial arithmitics number relative to now. |
[in] | now | number of seconds since epoch (midnight, January 1st, 1970) to which the time value is compared to determine the final value. |
[out] | result | the struct with the broken-out time information |
int ldns_init_random | ( | FILE * | fd, | |
unsigned int | size | |||
) |
Seed the random function.
If you need more entropy, or have no openssl available, this function MUST be called at the start of the program
If openssl *is* available, this function just adds more entropy
