Hi netters:

    In programming on dynamic memory allocation, I prefer doing check on
    every malloc(). I.e.:

    if ((p=(SOME_TYPE *)malloc(sizeof(SOME_TYPE))) == NULL) {
        printf("Malloc error.\n");
        exit(0);
    }

    It turned out it's a pain to type in the above four lines if I have
    lots of malloc() invocations in the program, also, the program looks
    ugly. So I tried to use a function called my_malloc():

    SOME_TYPE *my_malloc()
    {
        SOME_TYPE *p;

        if ((p=(SOME_TYPE *)malloc(sizeof(SOME_TYPE))) == NULL) {
            printf("Malloc error.\n");
            exit(0);
        }
        return(p);
    }

    However another problem arises, what if I have many distinct types
    of memory space to allocate? That is, I can't use the same type in
    calling my_malloc(). So how can I pass a type to a function?

    Thanks for your reponse.
