Brand new to C. I am trying to dynamically allocate the array frags2 of size numberOfFrags and copy over the contents of the original array to it. I have tried numerous approaches and searching and do not understand what is going wrong here. Sizeof on the new array returns 0 instead of what I thought I malloc'd. Any help would be much appreciated!

int main(int argc, const char* argv[]) {
 char* frags[MAX_FRAG_COUNT];  
 FILE* fp = fopen(argv[1], "r");
 int numberOfFrags = ReadAllFragments(fp, frags, MAX_FRAG_COUNT);
 fclose(fp);
 char** frags2 = (char**)malloc(numberOfFrags * sizeof(char*));
 for (int i = 0; i < numberOfFrags; i++) {
   frags2[i] = frags[i];
 }
 qsort(frags2, sizeof(frags2) / sizeof(char *), sizeof(char*), cstring_cmp);
