ck_bitmap_size(3)

Usage

#include <ck_bitmap.h>

unsigned int

ck_bitmap_size(unsigned int n_bits);

Library

Concurrency Kit (libck, -lck)

Overview

The ck_bitmap_size() function returns the number of bytes that are necessary to allocate for a bitmap that will contain the number of bits specified by n_bits.

This function is used to determine how many bytes to allocate for dynamically created bitmap objects. The allocated object must still be initialized using ck_bitmap_init(3).

Return values

This function returns a non-zero value.
