put file names in array

threre were some answers to my questions till now - no one was working
i need it for "c" program in windows!!!!!!!!

i get a  path of a directory called
"path_files" in a string
the function should read all the *.wrl files in the folder and put the names of the wrl files in an array of strings called
char **filebd;
i dont know how many files are in the folder.
i need to count them and put them in int - NO_OF_FILES
i need the function from the beginning including:
1)pointers declerations
2)malloc of the array of strings
3)making loop on all files and putting all the names in the array
4)especially 3!!!!!!

        dirlist[cur_size] = (char*) malloc(namelen+1);
        strcpy(dirlist[cur_size],dentry->d_name);
       
        cur_size++;
        if(cur_size>=max_size){
            max_size *= 2;
            dirlist=(char**)realloc(dirlist,max_size*sizeof(char*));
        }
    }
   
    closedir(d);
    for(i=0;i<cur_size;i++)
        printf("Entry #%d: %s\n",i,dirlist[i]);
   
    return 0;
}
 in windows... while compiling it retuns errors!!!
