{\footnotesize\ttfamily int osmo\+\_\+get\+\_\+rand\+\_\+id (\begin{DoxyParamCaption}\item[{uint8\+\_\+t $\ast$}]{out,  }\item[{size\+\_\+t}]{len }\end{DoxyParamCaption})}



Generate random identifier We use /dev/urandom (default when GRND\+\_\+\+RANDOM flag is not set). 

Both /dev/(u)random numbers are coming from the same CSPRNG anyway (at least on GNU/\+Linux $>$= 4.\+8). See also RFC4086. 
\begin{DoxyParams}[1]{Parameters}
\mbox{\texttt{ out}}  & {\em out} & Buffer to be filled with random data \\
\hline
\mbox{\texttt{ in}}  & {\em len} & Number of random bytes required \\
\hline
\end{DoxyParams}
\begin{DoxyReturn}{Returns}
0 on success, or a negative error code on error. 
\end{DoxyReturn}
