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. | |
const char * | ldns_version (void) |
Show the internal library version. | |
int | ldns_serial (uint32_t s1, uint32_t s2) |
Implements serial arith. | |
time_t | mktime_from_utc (const struct tm *tm) |
Convert TM to seconds since epoch (midnight, January 1st, 1970). |
