RAND_load_file(3) LibreSSL RAND_load_file(3)NAME
RAND_load_file, RAND_write_file, RAND_file_name - PRNG seed file
SYNOPSIS
#include <openssl/rand.h>
const char *RAND_file_name(char *buf, size_t num);
int RAND_load_file(const char *filename, long max_bytes);
int RAND_write_file(const char *filename);
DESCRIPTIONRAND_file_name() returns a default path for the random seed file. buf
points to a buffer of size num in which to store the filename. If num
is too small for the path name, an error occurs.
RAND_load_file() used to allow for the state of the random number
generator to be controlled by external sources.
It is kept for ABI compatibility but is no longer functional, and
should not used in new programs.
RAND_write_file() writes a number of random bytes (currently 1024) to
file filename.
RETURN VALUESRAND_load_file() always returns 0.
RAND_write_file() returns the number of bytes written, and -1 if the
bytes written were generated without appropriate seed.
RAND_file_name() returns a pointer to buf on success, and NULL on
error.
SEE ALSOrand(3), RAND_add(3), RAND_cleanup(3)HISTORYRAND_load_file(), RAND_write_file() and RAND_file_name() are available
in all versions of SSLeay and OpenSSL.
