ck_bitmap_init — initialize a bitmap
Contents
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).
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.
