Right. I overlooked that one.

Thanks,

I believe the function you want is RAND_status().

Apparently, there are some situations where there is no entropy source 
to seed the OpenSSL PRNG.


Is there a uniform way to detect that the OpenSSL PRNG has not been 
seeded? "Uniform" is uniform over the various platforms because I want 
to prevent that I need to check on a per platform basis whether an 
entropy source is lacking.
