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);
RAND_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 be used in new programs.
RAND_write_file() writes a number of random bytes (currently 1024) to file filename.
RAND_load_file() returns max_bytes, or a bogus positive value if max_bytes is -1.
RAND_write_file() returns the number of bytes written, or a number less than or equal to 1 if an error occurs.
RAND_file_name() returns a pointer to buf on success or
RAND_file_name() first appeared in SSLeay 0.5.1 and have been available since OpenBSD 2.4.
