ldns(3) Library Functions Manual ldns(3)

NAME
       ldnsinitrandom


SYNOPSIS
       #include 
       #include 

       #include 

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

DESCRIPTION
       ldnsinitrandom() 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
