SYNOPSIS

10       #include <stdint.h>
11       #include <stdbool.h>
12
13       #include <ldns/ldns.h>
14
15       int ldns_init_random(FILE *fd, unsigned int size);
16

DESCRIPTION

18       ldns_init_random() Seed the random function.  If the file descriptor is
19              specified, the random generator is seeded with  data  from  that
20              file. If not, /dev/urandom is used.
21
22              applications  should  call this if they need entropy data within
23              ldns If openSSL is available, it is  automatically  seeded  from
24              /dev/urandom or /dev/random.
25
26              If  you  need  more  entropy, or have no openssl available, this
27              function MUST be called at the start of the program
28
29              If openssl *is* available, this function just adds more entropy
30
31              fd: a file providing entropy data for the seed
32              size: the number of bytes to use as entropy data. If this is  0,
33              only the minimal amount is taken (usually 4 bytes)
34              Returns 0 if seeding succeeds, 1 if it fails
