=pod =head1 NAME RAND_egd - query entropy gathering daemon =head1 SYNOPSIS #include int RAND_egd(const char *path); =head1 DESCRIPTION RAND_egd() queries the entropy gathering daemon EGD on socket B. EGD is available from http://www.lothar.com/tech/crypto/ (C to install). It is run as B I, where I 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 . =head1 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. =head1 SEE ALSO L, L, L =head1 HISTORY RAND_egd() is available since OpenSSL 0.9.5. =cut
