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

              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
