Thread: Sorting a string linked list

I put some printf statements around

Code:

printf("Enter an unit name but not more than 100 characters:\n");
scanf("%s",buffer);
n=(char*)malloc(strlen(buffer)+1);
strcpy(n,buffer);
printf("n:%s and buffer:%s\n",n,buffer);
delete_it(n,the_list);

the function:

Code:

void delete_it(char *n, node_ptr list)
{
	node_ptr before = list;
	node_ptr current = list->next;
	printf("in list.c:%s",n);
	
	while(current != NULL)
	{
		if(strcmp(current->name, n) == 0)
		{
			before->next = current->next;
			free(current);
		}
		else
		{
			before = current;
			current = current->next;
		}
	}
	return;

Check these outputs:

OUTPUT1: "a" is in the list

Code:

Enter an unit name but not more than 100 characters:
a  
n:a and buffer:a
Segmentation fault

OUTPUT2: "c" is not in the list

Code:

Enter an unit name but not more than 100 characters:
c
n:c and buffer:c
in list.c:c
