pub fn mlockall(flags: MlockAllFlags) -> Result<()>Expand description
Locks all pages mapped into the address space of the calling process.
This includes the pages of the code, data, and stack segment, as well as shared libraries, user space kernel data, shared memory, and memory-mapped files. All mapped pages are guaranteed to be resident in RAM when the call returns successfully; the pages are guaranteed to stay in RAM until later unlocked.
