Synopsis
unsigned int bitmap_to_u32array ( | u32 * buf, |
| | unsigned int nwords, |
| | const unsigned long * bitmap, |
| | unsigned int nbits); |
Arguments
u32 * buf
array of u32 (in host byte order), the dest bitmap, non NULL
unsigned int nwords
number of u32 words in buf
const unsigned long * bitmap
array of unsigned longs, the source bitmap, non NULL
unsigned int 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.
