    A strange usage of # and sizeof.

    Hello everyone,


    I have found a very strange usage of # and sizeof from the following statement,

    Code:
    #define FOO(p) static const struct_goo p = { .length = sizeof(#p "\n")};
    What means "#p"? What is the meaning of the parameter -- #p "\n" -- passed to sizeof?


    thanks in advance,
    George
