For real-time applications it is generally advised
to avoid using dynamic memory allocation, but rather
to statically allocate the variables. Stack variables
are OK, heap variables are not because of the memory
management overhead, either manual or automatic.
As people keep saying, performance-wise "nothing
beats Fortran" where all variables are statically
declared, procedures are not reentrant,
and array indices are not checked at run time.
I am actually interested in this because my next project
will run on bare hardware. This is not related to our current
discussion of real-time Windows programming, though.
