NAME¶
ck_bitmap_init —
initialize a bitmap
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.
