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
- Parameters
-
| [in] | fd | a file providing entropy data for the seed |
| [in] | 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
Seed the random function.
If you need more entropy, or have no openssl available, this function MUST be called at the start of the program
