返回类型：int

参数：

类型参数名称
const char *buf
unsigned long *maskp
intnmaskbits
659  bitmap_zero(maskp, nmaskbits)
661  当buf循环
662  buf等于The format allows commas and whitespases at the beginning* of the region.
663  如果(buf == NULL)则返回:0
666  buf等于bitmap_parse_region(buf, & r)
667  如果是错误则返回:错误
670  ret等于bitmap_check_region( & r)
671  如果ret则返回:ret
674  ret等于bitmap_set_region( & r, maskp, nmaskbits)
675  如果ret则返回:ret
679  返回:0
