The system call establishes a page table for a specified length of memory starting from the specified start address, and maps to the idle user-State address space of the current program.Specific implementations can refer to the following sample code:char *vmem = NULL;FILE * fp= fopen ("/dev/mem", "w+");int fp = open ("/dev/m
