RAND_egd(3)		     OpenSSL		      RAND_egd(3)

NAME
       RAND_egd - query entropy gathering daemon

SYNOPSIS
	#include <openssl/rand.h>

	int RAND_egd(const char *path);

DESCRIPTION
       RAND_egd() queries the entropy gathering daemon EGD on
       socket path.

       EGD is available from http://www.lothar.com/tech/crypto/
       (perl Makefile.PL; make; make install to install). It is
       run as egd path, where path is an absolute path
       designating a socket. When RAND_egd() is called with that
       path as an argument, it tries to read random bytes that
       EGD has collected. The read is performed in non-blocking
       mode.

       Alternatively, the EGD-compatible daemon PRNGD can be
       used. It is available from http://www.aet.tu-
       cottbus.de/personen/jaenicke/postfix_tls/prngd.html .

RETURN VALUE
       RAND_egd() returns the number of bytes read from the
       daemon on success, and -1 if the connection failed or the
       daemon did not return enough data to fully seed the PRNG.

SEE ALSO
       rand(3), RAND_add(3), RAND_cleanup(3)

HISTORY
       RAND_egd() is available since OpenSSL 0.9.5.
