Subject: Nulls in scalar parameters
Date: Thu, 20 Oct 2022 23:50:53 -0500	[thread overview]
Message-ID: <cc0b034e-056d-3da6-e69b-55b447a6c235@zentaur.org> (raw)

I'm working on a zsh/random module and I'm creating a builtin that 
returns a user-specified number of random bytes and either prints it or 
returns it in a parameter.  There exists a small possibility of embedded 
nulls in the output, and I'm not sure how to handle setting such a value 
in a parameter.

One solution is to make it return a hex string, but I'm not sure of the 
utility of such a result.

Metafy looks like it would handle the null problem, but I'm not sure 
what else it does nor how that would play out if printed to a file.

P.S. to be clear, this module would return random data drawn from the 
kernel's entropy pool, rather than a predictable pseudo-random generator 
like rand or erand48
