This is a header-only library, as such most of its functional documentation is contained within the "header section" of the source code in the form of comments. It is highly recommended that you read said documentation before using this library.


The dynarr library provides type-generic general-purpose array data structures, its features include:

  • No hard dependencies besides the standard library, making it fully portable for most purposes
  • Configurable memory allocation function, allowing for compatibility with custom memory managers
  • Usable as a stack, queue, dynamic array, binary-searchable list, or all of the above at once
  • Supports sorting using either its own linear sort or the standard qsort implemenetation


#define DYNARR_STATIC //static version
#include "dynarr.h" //include dynarr
#include <stdio.h> //printf

static int sortInt(const int*, const int*);

int main () {
    //declare and initialize dynarr
    int* darr = DYNARR_NEW(int);
    //push a couple of elements
    DYNARR_PUSH(darr, 4);
    DYNARR_PUSH(darr, 1);
    DYNARR_PUSH(darr, 3);
    DYNARR_PUSH(darr, 2);
    //sort dynarr in ascending order
    DYNARR_SORT_STD(darr, sortInt);
    //iterate through the dynarr and print its elements
    for (int i = 0; i < DYNARR_SIZE(darr); i++)
        printf("darr[%d] = %d\n", i, DYNARR_AT(darr, i));
    //free the dynarr
    return 0;

static int sortInt (const int* a, const int* b) {
    return *a-*b; //ascending order
