ck_bitmap_buffer(3)

Usage

#include <ck_bitmap.h>

void *

ck_bitmap_buffer(ck_bitmap_t *bitmap);

Library

Concurrency Kit (libck, -lck)

Overview

The ck_bitmap_buffer() functions returns a pointer to the actual bit array. For ck_bitmap pointers, the bit array is of type CK_BITMAP_WORD[] and consists of ck_bitmap_base(bitmap) / sizeof(CK_BITMAP_WORD) elements. On currently supported 64-bit platforms CK_BITMAP_WORD is uint64_t. On currently supported 32-bit platforms CK_BITMAP_WORD is uint32_t.

Return values

This function returns a non-NULL value.
