BITMAP_TO_U32ARRAY(9)             Basic Kernel Library Functions            BITMAP_TO_U32ARRAY(9)



NAME
       bitmap_to_u32array - copy the contents of bitmap to a u32 array of bits

SYNOPSIS
       unsigned int bitmap_to_u32array(u32 * buf, unsigned int nwords,
                                       const unsigned long * bitmap, unsigned int nbits);

ARGUMENTS
       buf
           array of u32 (in host byte order), the dest bitmap, non NULL

       nwords
           number of u32 words in buf

       bitmap
           array of unsigned longs, the source bitmap, non NULL

       nbits
           number of bits in bitmap

DESCRIPTION
       copy min(nbits, 32*nwords) bits from bitmap to buf. Remaining bits after nbits in buf (if
       any) are cleared.

       Return the number of bits effectively copied.
