How define an array of function pointers in C

Question

I\'ve a little question. I\'m trying to define an array of function pointers dynamically with calloc. But I don\'t know how to write the syntax. Thanks a lot.<

Assuming all your functions are of type void ()(void), something like this

typedef void (*fxptr)(void);
fxptr *ptr; // pointer to function pointer
ptr = malloc(100 * sizeof *ptr);
if (ptr) {
    ptr[0] = fx0;
    ptr[1] = fx1;
    /* ... */
    ptr[99] = fx100;

    /* use "dynamic array" of function pointers */

    free(ptr);
}
