Name:__bitmap_set
Proto:void __bitmap_set(unsigned long *map, unsigned int start, int len)
Type:void
Parameter:
| Type | Parameter | Name |
|---|---|---|
| unsigned long * | map | |
| unsigned int | start | |
| int | len |
| 286 | bits_to_set = BITS_PER_LONG - start % BITS_PER_LONG |
| 289 | When len - bits_to_set >= 0 cycle |
| 290 | p |= mask_to_set |
| 291 | len -= bits_to_set |
| 292 | bits_to_set = BITS_PER_LONG |
| 293 | mask_to_set = ~0UL |
| 294 | p++ |
| 296 | If len Then |
| 297 | mask_to_set &= BITMAP_LAST_WORD_MASK(size) |
| 298 | p |= mask_to_set |
