NAME

6       bitmap_to_u32array - copy the contents of bitmap to a u32 array of bits
7

SYNOPSIS

9       unsigned int bitmap_to_u32array(u32 * buf, unsigned int nwords,
10                                       const unsigned long * bitmap,
11                                       unsigned int nbits);
12

ARGUMENTS

14       buf
15           array of u32 (in host byte order), the dest bitmap, non NULL
16
17       nwords
18           number of u32 words in buf
19
20       bitmap
21           array of unsigned longs, the source bitmap, non NULL
22
23       nbits
24           number of bits in bitmap
25

DESCRIPTION

27       copy min(nbits, 32*nwords) bits from bitmap to buf. Remaining bits
28       after nbits in buf (if any) are cleared.
29
30       Return the number of bits effectively copied.
