Name:find_next_clump8

Proto:unsigned long find_next_clump8(unsigned long *clump, const unsigned long *addr, unsigned long size, unsigned long offset)

Type:unsigned long

Parameter:

TypeParameterName
unsigned long *clump
const unsigned long *addr
unsigned longsize
unsigned longoffset
221  offset = Find the next set bit in a memory region.
222  If offset == size Then Return size
225  offset = und_down - round down to next specified power of 2*@x: the value to round*@y: multiple to round down to (must be a power of 2)* Rounds @x down to next multiple of @y (which must be a power of 2).* To perform arbitrary rounding down, use rounddown() below.(offset, 8)
226  clump = map_get_value8 - get an 8-bit value within a memory region*@map: address to the bitmap memory region*@start: bit offset of the 8-bit value; must be a multiple of 8* Returns the 8-bit value located at the @start bit offset within the @src* memory region.
228  Return offset
