CommsMemFree(1) = tiny + lil*100 + mid*10000 + med*1000000 +
lrg*100000000
where,
tiny = number of 16‐byte packets available
lil = number of little (≈100 bytes) packets
mid = number of medium size (≈530 bytes) packets
med = number of big (≈3 kB) packets
lrg = number of large (≈18 kB) packets available, primarily for TLS.
The following expressions are used to pick the individual values from
CommsMemFree(1):
tiny = CommsMemFree(1) % 100
lil = (CommsMemFree(1) / 100) % 100
mid = (CommsMemFree(1) / 10000) % 100
med = (CommsMemFree(1) / 1000000) % 100
lrg = (CommsMemFree(1) / 100000000) % 100
