An .mmap file is a file format created by Mindjet for it’s mind mapping software, MindManager. These mmap files are also referred to as memory files, mind maps, etc. They can contain many different elements such as images, icons, equations, text, symbols, and more.

A memory-mapped file is a segment of virtual memory [1] that has been assigned a direct byte-for-byte correlation with some portion of a file or file-like resource. This resource is typically a file that is physically present on disk, but can also be a device, shared memory object, or other resource that an operating system can reference ...

MAP_PRIVATE mappings require a memory reservation, as writing to these pages may result in copy-on-write allocations. This means that you can't map something too much larger than your physical ram + swap. Try using a MAP_SHARED mapping instead.

Jun 12, 2018 · mmap() uses addresses outide your program's heap area, so heap fragmentation isn't a problem, except to the extent that it can make the heap take up more space, and reduce the available space for mappings.

Nov 3, 2008 · You can mmap a file as read / write in the processes that need to communicate and then use synchronization primitives in the mmap'd region (this is what the MAP_HASSEMAPHORE flag is for). One place mmap can be awkward is if you need to work with very large files on a 32 bit machine.

Dec 30, 2024 · mmap (memory-mapped file) is a system call that maps a file or a portion of it into a process’s virtual memory space. This allows a program to directly access file data as if it were part of the program’s memory, bypassing explicit read and write system calls.
