Equivalent to the list 'push' notion, thus if librdf_list_pop() is called after this, it will return the value added here. list : librdf_list object data : the data value Returns : non 0 on failure librdf_list_unshiftint librdf_list_unshift (librdf_list *list, void *data); Add a data item to the start of a librdf_list. if librdf_list_shift() is called after this, it will return the value added here. list : librdf_list object data : the data value Returns : non 0 on failure librdf_list_shiftvoid* librdf_list_shift (librdf_list *list); Remove and return the data at the start of the list. list : librdf_list object Returns : the data object or NULL if the list is empty librdf_list_popvoid* librdf_list_pop (librdf_list *list); Remove and return the data at the end of the list. list : librdf_list object Returns : the data object or NULL if the list is empty librdf_list_removevoid* librdf_list_remove (librdf_list *list, void *data); Remove a data item from an librdf_list. The search is done using the 'equals' function which may be set by librdf_list_set_equals() or by straight comparison of pointers if not set. list : librdf_list object data : the data item Returns : the data stored or NULL on failure (not found or list empty) librdf_list_containsint librdf_list_contains (librdf_list *list, void *data); Check for presence of data item in list. The search is done using the 'equals' function which may be set by librdf_list_set_equals() or by straight comparison of pointers if not set. list : librdf_list object data : the data value Returns : non 0 if item was found librdf_list_sizeint librdf_list_size (librdf_list *list); Return the length of the list. list : librdf_list object Returns : length of the list librdf_list_set_equalsvoid librdf_list_set_equals (librdf_list *list, int (*equals) (void* data1, void *data2)); Set the equals function for the list. The function given is used when comparing items in the list during searches such as those done in librdf_list_remove() or librdf_list_contains(). list : librdf_list object equals : the equals function librdf_list_get_iteratorlibrdf_iterator* librdf_list_get_iterator (librdf_list *list); Get an iterator for the list. list : librdf_list object Returns : a new librdf_iterator object or NULL on failure librdf_list_foreachvoid librdf_list_foreach (librdf_list *list, void (*fn) (void *, void *), void *user_data); Apply a function for each data item in a librdf_list. list : librdf_list object fn : pointer to function to apply that takes data pointer and user data parameters user_data : user data for applied function
