Who not create abstract framework for work with bitmask more then 64bits
size?=20
similar this:
#define_bitmask(name,size) char name[(size/8)+1];
#define set_bit(bimask,no) { bitmask[(no/8)] |=3D 1<<(no%8); }
#define clr_bit(bitmask,no) { bitmask[(no/8)] &=3D ~(1<<(no%8)); }
static inline isset_bit(char *bitmask, no) {
return bitmask[(no/8)] & 1<<(no%8);
}
--=20
