MemoryConstrained

evaluates expr, stopping if more than b bytes of memory are requested.

returns failexpr if the memory constraint is not met.

Details

MemoryConstrained generates an interrupt to stop the evaluation of expr if the amount of additional memory requested during the evaluation of expr exceeds b bytes.
MemoryConstrained evaluates failexpr only if the evaluation is aborted.
MemoryConstrained returns $Aborted if the evaluation is aborted and no failexpr is specified.
Aborts generated by MemoryConstrained can be overruled by AbortProtect. »
MemoryConstrained[expr,Infinity] imposes no memory constraint.

Run a command until a memory limit is exceeded:

The loop ran until memory allocation for the result of Range exceeded the limit:

Specify the value to return if the time constraint is reached:

Use CheckAbort inside MemoryConstrained to select which parts are skipped if the limit is reached:

The third argument is only evaluated if the memory limit is reached:

A nested AbortProtect can block the action of MemoryConstrained:

An enclosing AbortProtect is overridden by MemoryConstrained:

While code inside the MemoryConstrained is terminated, AbortProtect runs to completion:

MemoryConstrained can constrain the first argument of CheckAbort, but not the second:
