Name	nbfread
Definition	nbfread(f:val(bfile),data:var(T:type)) : expr(bool).
Defined in	io.l
Implementation	builtin
Description	Read enough bytes from the given non-blocking binary file to fill the variable data.
Note	The interpretation of the data depends on the host byte order. Reading strings using this function will not work. If no bytes are available to read thn do not block just return false. As soon as data is available block until the entire variable has been read then return true. This function can be most easily used with a wait_until loop. e.g. wait_until (nbfread (somefile, somevariable)) will perform a polled read of the file somefile without blocking other LARD threads.
