WebMemory mapping is the translation between the logical address space and the physical memory. The objectives of memory mapping are (1) to translate from logical to physical address, (2) to aid in memory protection (q.v.), and (3) to enable better management of memory resources.

"WebMemory mapping is one of the most interesting features of a Unix system. From a driver's point of view, the memory-mapping facility allows direct memory access to a user space device. To assign a mmap () operation to a driver, the mmap field of the device driver's struct file_operations must be implemented. " - Memory map ldd

Shared library mappings in /proc/pid/maps - linux

WebMapped memory regions, also called shared memory areas, can serve as a large pool for exchanging data among processes. The available subroutines do not provide locks or access control among the processes. Therefore, processes using shared memory areas must set up a signal or semaphore control method to prevent access conflicts and to keep WebLD.SO(8) Linux Programmer's Manual LD.SO(8) NAME top ld.so, ld-linux.so - dynamic linker/loader SYNOPSIS top The dynamic linker can be run either indirectly by running some dynamically linked program or shared object (in which case no command-line options to the dynamic linker can be passed and, in the ELF case, the dynamic linker which is stored in …
