CK_BITMAP_INIT(3)     DragonFly Library Functions Manual     CK_BITMAP_INIT(3)

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.
