NAME
ldns_init_random - seed the random function
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
.br
fd: a file providing entropy data for the seed
.br
size: the number of bytes to use as entropy data. If this is 0,
only the minimal amount is taken (usually 4 bytes)
.br
Returns 0 if seeding succeeds, 1 if it fails
