![]() Updates to the mapping are not visible to other processes mapping the same file, and are not carried through to the underlying file. This mapping type is also required to be able to use some mapping flags (e.g., MAP_SYNC). This flag provides the same behavior as MAP_SHARED except that MAP_SHARED mappings ignore unknown flags in flags.īy contrast, when creating a mapping using MAP_SHARED_VALIDATE, the kernel verifies all passed flags are known and fails the mapping with (To precisely control when updates are carried through to the underlying file requires the use of msync(2).) Updates to the mapping are visible to other processes mapping the same region, and (in the case of file-backed mappings) are carried through to the This behavior is determined by including exactly one of the following values in flags. ![]() The flags argument determines whether updates to the mapping are visible to other processes mapping the same region, and whether updates are carried
