NAME¶

ldns_init_random

SYNOPSIS¶

#include <stdint.h>
#include <stdbool.h>

#include <ldns/ldns.h>

int ldns_init_random(FILE *fd, unsigned int size);

DESCRIPTION¶

ldns_init_random() 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

fd: a file providing entropy data for the seed
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
