pointers and dynamic memory allocation.

How can I read a line of text and spaces and replace each space in the line with 3 stars dynamically?

Note: check the syntax - could have typos

FILE *in;
char *buf,tmp[256],*s;
char stars[512];
int i;
in=fopen("myfile","r");
while(!feof(in)){
         *tmp=0x00;
         if(fgets(tmp,255,in)!=NULL){
                  memset(stars,0x00,512);
                  for(buf=tmp,s=stars;*buf;buf++)
                            if(*buf==0x20)
                                  for(i=0;i<3;i++) *s++='*';
                            else 
                                  *s++=*buf;
         // stars now has the spaces replaced with three *
        // do something with the string stars
         }
}
fclose(in);
