• https://github.com/tezc/sc
• https://github.com/KaisenAmin/c_std
• https://github.com/postgres/postgres/blob/master/src/backend/lib/rbtree.c

Usage

sudo make install
export LIBRARY_PATH=/usr/local/lib

# Use libcp
gcc your_code.c -l cp

# Generate an independent file with the suffix _combined.c

Library list

• sds: A simplification of Redis SDS
• vector: dynamic array, can be used as stack
• deque: double-ended queue, can be used as queque
• heap: binary heap, for priority_queue
• dict: open addressing hash table, for unordered_set and unordered_map
• rbtree: red-black tree, for map
• bitset

No implementation

• list: doubly-linked list, fast insertion in the middle, but slow positioning
