+/** @fn  ftok(const char *pathname, int proj_id)
+@param pathname
+@param proj_id
+@return   The ftok function will return -1 if pathname does not exist or if it cannot be accessed by the calling process.
+On  success  the  generated key_t value is returned.
+
+  The ftok function attempts to create a unique key suitable for use with the msgget , semget and shmget functions given the pathname of an existing file and a user-selectable id.
+
+ The specified pathname must specify an existing file that is accessible to the calling process
+or the call will fail.
+Also, note that links to files will return the
+same key, given the same id.
+
+Examples:
+@code
+#include <sys/types.h>
+#include <sys/ipc.h>
+#include <stdio.h>
+
+int main(void)
+{
+    char *pathame = "C:\XXX";
+    int proj_id = 100;
+    key_t fkey;
+    if ((fkey = ftok(pathame, proj_id)) == -1) {
+        printf("ftok() failed
+");
+    }
+    return 0;
