LIBRARY
Concurrency Kit (libck, -lck)
SYNOPSIS
#include
<ck_bitmap.h>
void
ck_bitmap_init
(ck_bitmap_t
*bitmap, unsigned int
n_bits, bool
set);
DESCRIPTION
The
ck_bitmap_init
()
function initializes the bitmap pointed to by the
bitmap pointer. The argument
n_bits specifies the number of bits that are to be
stored in the bitmap. The argument set determines
whether the values of the bits in bitmap are to be
initialized to 1
or 0
.
It is expected that bitmap points to a contiguous region of memory containing at least the number of bytes specified by ck_bitmap_size(3).
RETURN VALUES
This function has no return value.
ERRORS
The behavior of ck_bitmap_init
() is
undefined if bitmap is not a pointer to a region of
bytes of at least
ck_bitmap_size(3)
length.
