RAND_load_file(3SSL) OpenSSL RAND_load_file(3SSL)NAME
RAND_load_file, RAND_write_file, RAND_file_name - PRNG seed file
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);
RAND_file_name() generates a default path for the random seed file. buf points to a buffer of size num in which to store the filename. The
seed file is $RANDFILE if that environment variable is set, $HOME/.rnd otherwise. If $HOME is not set either, or num is too small for the
path name, an error occurs.
RAND_load_file() reads a number of bytes from file filename and adds them to the PRNG. If max_bytes is non-negative, up to to max_bytes are
read; starting with OpenSSL 0.9.5, if max_bytes is -1, the complete file is read.
RAND_write_file() writes a number of random bytes (currently 1024) to file filename which can be used to initialize the PRNG by calling
RAND_load_file() in a later session.
RAND_load_file() returns the number of bytes read.
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.

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.
# When the shell exits, append to the history file instead of overwriting it
