boost::interprocess::xsi_key
// In header: <boost/interprocess/xsi_key.hpp> class xsi_key { public: // construct/copy/destruct xsi_key(); explicit xsi_key(key_t); xsi_key(const char *, boost::uint8_t); // public member functions key_t get_key() const; };
A class that wraps XSI (System V) key_t type. This type calculates key_t from path and id using ftok, sets key to a specified value, or sets key to IPC_PRIVATE using the default constructor.
xsi_key
public
construct/copy/destructxsi_key();
Default constructor. Represents a private xsi_key.
explicit xsi_key(key_t key);Creates a new XSI key using a specified value. Constructor is explicit to avoid ambiguity with shmid.
xsi_key(const char * path, boost::uint8_t id);
Creates a new XSI shared memory with a key obtained from a call to ftok (with path "path" and id "id"), of size "size" and permissions "perm". If the shared memory previously exists, throws an error.
