+### csort - two times faster qsort
+
+When very fast array sorting is required, **csort** is about twice as fast as *qsort()*, and often simpler to use.
+You may customize `i_tag` and the comparison function `i_cmp` or `i_less`.  
+
+There is a [benchmark/test file here](../misc/benchmarks/various/csort_bench.c).
+```c
+#define i_val int
+#include <stc/algo/csort.h>
+
+int main() {
+    int array[] = {5, 3, 5, 9, 7, 4, 7, 2, 4, 9, 3, 1, 2, 6, 4};
+    csort_int(array, c_arraylen(array));
+}
+```
