Sort of Structs

Function to Sort a struct-array called „adres“ after namewise, with holding additional fields together

void Sort(struct adres sort[], int nr) {
   int i,j;
   struct adres *temp;
   temp = (struct adres *)malloc(sizeof(struct adres *));
   if(NULL == temp) {
      printf("Konnte keinen Speicher reservieren...\n");
      return;
   }
   for(i = 0; i < nr; i++) {
      for(j=i+1;j<nr;j++) {
         if(strcmp(sort[i].nname, sort[j].nname) > 0) { /*could be a "a < i" operation for numberwise sorting of rankings or smth*/
            *temp=sort[j];
            sort[j]=sort[i];
            sort[i]=*temp;
         }
      }
   }
   printf(".....Sortiert!!\n\n");
