/*
* Query the EGD <URL: http://www.lothar.com/tech/crypto/>.
*
* This module supplies three routines:
*
* RAND_query_egd_bytes(path, buf, bytes)
* will actually query "bytes" bytes of entropy form the egd-socket located
* at path and will write them to buf (if supplied) or will directly feed
* it to RAND_seed() if buf==NULL.
* The number of bytes is not limited by the maximum chunk size of EGD,
* which is 255 bytes. If more than 255 bytes are wanted, several chunks
* of entropy bytes are requested. The connection is left open until the
* query is competed.
* RAND_query_egd_bytes() returns with
* -1 if an error occured during connection or communication.
* num the number of bytes read from the EGD socket. This number is either
* the number of bytes requested or smaller, if the EGD pool is
* drained and the daemon signals that the pool is empty.
* This routine does not touch any RAND_status(). This is necessary, since
* PRNG functions may call it during initialization.
*
* RAND_egd_bytes(path, bytes) will query "bytes" bytes and have them
* used to seed the PRNG.
* RAND_egd_bytes() is a wrapper for RAND_query_egd_bytes() with buf=NULL.
* Unlike RAND_query_egd_bytes(), RAND_status() is used to test the
* seed status so that the return value can reflect the seed state:
* -1 if an error occured during connection or communication _or_
* if the PRNG has still not received the required seeding.
* num the number of bytes read from the EGD socket. This number is either
* the number of bytes requested or smaller, if the EGD pool is
* drained and the daemon signals that the pool is empty.
*
* RAND_egd(path) will query 255 bytes and use the bytes retreived to seed
* the PRNG.
* RAND_egd() is a wrapper for RAND_egd_bytes() with numbytes=255.
