BITMAP_FIND_NEXT_ZER(9) | Basic Kernel Library Functions | BITMAP_FIND_NEXT_ZER(9) |
NAME¶
bitmap_find_next_zero_area_off - find a contiguous aligned zero area
SYNOPSIS¶
unsigned long bitmap_find_next_zero_area_off(unsigned long * map, unsigned long size, unsigned long start, unsigned int nr, unsigned long align_mask, unsigned long align_offset);
ARGUMENTS¶
unsigned long * map
unsigned long size
unsigned long start
unsigned int nr
unsigned long align_mask
unsigned long align_offset
DESCRIPTION¶
The align_mask should be one less than a power of 2; the effect is that the bit offset of all zero areas this function finds plus align_offset is multiple of that power of 2.
