What is the function of the CreateFileMapping function?

The CreateFileMapping function is used to create a file mapping object in the virtual address space of a process, which allows mapping a disk file or other device to the process’s memory. This function can map a disk file to the process’s address space, allowing the process to access the file’s content directly without performing read and write operations. Once the mapping object is created, the MapViewOfFile function can be used to associate the mapping object to the process’s memory address space, enabling direct reading and writing of file data through pointers.
