What is the simplest way to monitor how much memory is still free. My program just seems to terminate silently when the paging file is exhausted. I know that the paging file is used-up based on the accounting information logs.

Use sys$getjpi[w] to monitor the current usage, and sys$getjpi[w] and sys$getuai to retrieve the specified limits. Obviously, check for a null return from the malloc call. Consider using private memory management, based on calls to the RTL LIB$GET_VM services. The LIB$GET_VM services are far more flexible and powerful than the standard C memory management tools. | |||||
