Body
I have a structure, <pre><code> typedef struct song{ string title; string artist; string album; string genre; float rating; struct song *next; }song_t; </code></pre> and a delete function, <pre><code> song_t *DeleteSong(song_t *head, string key){ song_t *temp, *temp2, *holder; holder = (song_t *)malloc(sizeof(song_t)); temp = head; while(temp != NULL && strcasecmp(temp->title, key) != 0){ temp = temp->next; } if(temp == NULL){ newline; printf("Song not found."); newline; newline; } else if(temp == head){ if(temp->next == NULL){ temp->next = NULL; free(temp); return NULL; } else{ head = temp->next; } } else if(temp->next == NULL){ temp2 = head; while(temp2->next->next != NULL){ temp2 = temp2->next; } holder = temp2->next->next; temp2->next = NULL; } else{ temp2 = head; while(temp2->next != temp){ temp2 = temp2->next; } holder = temp; temp2->next = temp->next; free(holder); } return head; } </code></pre> and finally, a remove duplicate function, <pre><code>song_t *RemoveDuplicate(song_t *head){ song_t *temp; song_t *temp2; temp = head; temp2 = temp->next; while(temp != NULL){ while(temp2 != NULL){ if(strcasecmp(temp->title,temp2->title) == 0 && strcasecmp(temp->artist,temp2->artist) == 0 && strcasecmp(temp->album,temp2->album) == 0 && strcasecmp(temp->genre,temp2->genre) == 0){ if(temp2 == temp->next){ temp = DeleteSong(temp,temp2->title); } else{ temp2 = DeleteSong(temp2->next,temp2->title); } } temp2 = temp2->next; } temp = temp->next; } } </code></pre> However, whenever I include the remove duplicate function in main, head = RemoveDuplicate(head); the result always returns only one structure and removes the whole list. I think that there is something wrong with the RemoveDuplicate function because I tested the DeleteSong function and it works well.

1. COIn the else statement I don't understand why you are passing temp2->next as head pointer. And after the `temp=temp->next` (after the inner while) shouldn't you put `temp2=temp->next;`?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
