Simple pure C data structures

libds - datastructures

libds is a library providing simple datastructures. It is designed to be portable (to the point only requiring memory allocation and ffreestanding environment).

Provided data structures

• ds/random.h - random number generator
• ds/array.h - resizable array list
• ds/btree.h - ballanced tree (red/black tree)
• ds/hmap.h - hashmap
• ds/queue.h - (FIFO) queue
• ds/funcops.h - standard function interfaces used by previous data structures (along with some defined concrete functions)

Requirements

libds requires these headers to be present at build environment:

• <stdbool.h>
• <stddef.h>
• <stdint.h>

libds also requires these extern functions:

• extern void* malloc(size_t n)
• extern void* calloc(size_t num, size_t n)
• extern void* realloc(void* a, size_t n)
• extern void free(void* a)
• extern int strcmp(const char* a, const char* b)
• extern void* memset(void* c, int v, size_t s)

Building libds

To build libds, simply invoke make all in the root directory. You will need to provide suitable SYSROOT argument or a PREFIX argument. INCLUDE argument can be overwritten to change where headers will be copied to (they will always be in INCLUDE/ds directory).
