Pushing the Limits of Windows: Handles. A Windows process is essentially container that hosts the execution of an executable image file. Processes operate with a security context, called a token, that identifies the user account, account groups, and privileges assigned to the process. Besides basic information about a thread, including its CPU register state, scheduling priority, and resource usage accounting, every thread has a portion of the process address space assigned to it, called a stack, which the thread can use as scratch storage as it executes program code to pass function parameters, maintain local variables, and save function return addresses.

Because stacks grow downward in memory, the system places guard pages beyond the committed part of the stack that trigger an automatic commitment of additional memory called a stack expansion when accessed. The linker defaults to a reserve of 1MB and commit of one page 4K , but developers can override these values either by changing the PE values when they link their program or for an individual thread in a call to CreateThread. You can use a tool like Dumpbin that comes with Visual Studio to look at the settings for an executable.

Even if the thread had no code or data and the entire address space could be used for stacks, a bit process with the default 2GB address space could create at most 2, threads.

Again, since part of the address space was already used by the code and initial heap, not all of the 2GB was available for thread stacks, thus the total threads created could not quite reach the theoretical limit of 2, The reason for the discrepancy comes from the fact that when you run a bit application on bit Windows, it is actually a bit process that executes bit code on behalf of the bit threads, and therefore there is a bit thread stack and a bit thread stack area reserved for each thread.

I got different results when I ran bit Testlimit on bit Windows 7, however:. Greg Shultz is a freelance Technical Writer.
