boost::interprocess::permissions
// In header: <boost/interprocess/permissions.hpp> class permissions { public: // construct/copy/destruct permissions(os_permissions_type) noexcept; permissions() noexcept; // public member functions void set_default() noexcept; void set_unrestricted() noexcept; void set_permissions(os_permissions_type) noexcept; os_permissions_type get_permissions() const noexcept; };
The permissions class represents permissions to be set to shared memory or files, that can be constructed form usual permission representations: a SECURITY_ATTRIBUTES pointer in windows or ORed rwx chmod integer in UNIX.
permissions public member functionsvoid set_default() noexcept;
Sets permissions to default values: A null security attributes pointer for windows or 0644 for UNIX.
void set_unrestricted() noexcept;
Sets permissions to unrestricted access: A null DACL for windows or 0666 for UNIX.
void set_permissions(os_permissions_type perm) noexcept;
Sets permissions from a user provided os-dependent permissions.
os_permissions_type get_permissions() const noexcept;
Returns stored os-dependent permissions
