The APIs provided by Redis

(i) string SDS

1) Sdsnew: Create a SDS containing the given C string

2) Sdsempty: Create an empty SDS that does not contain any content

3) Sdsfree: Release of the given SDS

4) Sdslen: Number of bytes of used space returned to SDS

5) Sdsavail: The number of unused space bytes returned by SDS

6) Sdsdup: Create a copy of a given SDS (copy)

7) Sdsclear: Empty the contents of SDS-Saved strings

8) Sdscat: Stitching the given C string to the end of the SDS string

9) Sdscatsds: Stitching the given SDS string to the end of another SDS string

sdscpy: Copy the given C string into the SDS, overwriting the original SDS string

Sdsgrowzero: Extend SDS to a given length with null characters

Sdsrange: Preserves data within a given interval of SDS, and data that is not within the interval is overwritten or cleared

Sdstrim: Receives an SDS and a C string as a parameter, removing all occurrences of the characters in the C string from the left and right sides of the SDS, respectively

SDSCMP: Comparison of two SDS strings

(ii) linked list

1) Listsetdupmethod: Sets the given function to the node value copy function of the linked list

2) Listgetdupmethod: Returns the node value copy function that is currently in use by the list

3) Listsetfreemethod: Sets the given function to the node value deallocation function of the linked list

4) Listgetfree: Returns the node value release function that is currently in use by the list

5) Listsetmatchmethod: Sets the given function to the node value comparison function of the linked list

6) Listgetmatchmethod: Returns the node value comparison function that is currently in use by the list

7) Listlength: Returns the length of the linked list (contains the number of nodes)

8) Listfirst: Returns the table header node of the linked list

9) Listlast: Returns the footer node of the linked list

Listprevnode: Returns the predecessor node of a given node

Listnextnode: Returns the backend node for a given node

Listnodevalue: Returns the value currently being saved for the given node

Listcreate: Create a new linked list that does not contain any nodes

Listaddnodehead: Adds a new node with the given value to the table header for the given list

Listaddnodetail: Adds a new node with a given value to the footer of a given list

Listinsertnode: Adds a new node with the given value before or after the given node

Listsearchkey: Query and return the node containing the given value in the linked list

ListIndex: Returns the node of the linked list on the given index

Listdelnode: Remove the given node from the list

Listrotate: POPs the footer node of the list, and then inserts the node that is popped into the table header of the linked list, becoming the new header node

Listdup: Copy a copy of a given list

Listrelease: Releases the given list, and all nodes in the linked list
