Functions |
ldns_lookup_table * | ldns_lookup_by_name (ldns_lookup_table table[], const char *name) |
| Looks up the table entry by name, returns NULL if not found.
|
ldns_lookup_table * | ldns_lookup_by_id (ldns_lookup_table table[], int id) |
| Looks up the table entry by id, returns NULL if not found.
|
int | ldns_get_bit (uint8_t bits[], size_t index) |
| Returns the value of the specified bit The bits are counted from left to right, so bit #0 is the left most bit.
|
int | ldns_get_bit_r (uint8_t bits[], size_t index) |
| Returns the value of the specified bit The bits are counted from right to left, so bit #0 is the right most bit.
|
void | ldns_set_bit (uint8_t *byte, int bit_nr, bool value) |
| sets the specified bit in the specified byte to 1 if value is true, 0 if false The bits are counted from right to left, so bit #0 is the right most bit.
|
int | ldns_hexdigit_to_int (char ch) |
| Returns the int value of the given (hex) digit.
|
char | ldns_int_to_hexdigit (int ch) |
| Returns the char (hex) representation of the given int.
|
int | ldns_hexstring_to_data (uint8_t *data, const char *str) |
| Converts a hex string to binary data.
|
const char * | ldns_version (void) |
| Show the internal library version.
|
time_t | mktime_from_utc (const struct tm *tm) |
| Convert TM to seconds since epoch (midnight, January 1st, 1970).
|
struct tm * | ldns_serial_arithmitics_gmtime_r (int32_t time, time_t now, struct tm *result) |
| The function interprets time as the number of seconds since epoch with respect to now using serial arithmitics (rfc1982).
|
int | ldns_init_random (FILE *fd, unsigned int size) |
| Seed the random function.
|
uint16_t | ldns_get_random (void) |
| Get random number.
|
char * | ldns_bubblebabble (uint8_t *data, size_t len) |
| Encode data as BubbleBabble.

int | b32_ntop_extended_hex (uint8_t const *src, size_t srclength, char *target, size_t targsize) |
int | ldns_b32_pton (char const *src, size_t hashed_owner_str_len, uint8_t *target, size_t targsize) |
int | b32_pton (char const *src, size_t hashed_owner_str_len, uint8_t *target, size_t targsize) |

int | b32_pton_extended_hex (char const *src, size_t hashed_owner_str_len, uint8_t *target, size_t targsize) |
Seed the random function.
If the file descriptor is specified, the random generator is seeded with data from that file. If not, /dev/urandom is used.
applications should call this if they need entropy data within ldns If openSSL is available, it is automatically seeded from /dev/urandom or /dev/random.
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
- Parameters:
-
[in] | fd | a file providing entropy data for the seed |
[in] | size | the number of bytes to use as entropy data. If this is 0, only the minimal amount is taken (usually 4 bytes) |
- Returns:
- 0 if seeding succeeds, 1 if it fails
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
