bitmap_from_u32array9
Copy the contents of a u32 array of bits to bitmap
Usage
unsigned int bitmap_from_u32array(unsigned long * bitmap, unsigned int nbits, const u32 * buf, unsigned int nwords);
Arguments
bitmap
array of unsigned longs, the destination bitmap, non NULL
nbits
number of bits in bitmap
buf
array of u32 (in host byte order), the source bitmap, non NULL
nwords
number of u32 words in buf
Overview
copy min(nbits, 32*nwords) bits from buf to bitmap, remaining bits between nword and nbits in bitmap (if any) are cleared. In last word of bitmap, the bits beyond nbits (if any) are kept unchanged.
Return the number of bits effectively copied.
