: Who not create abstract framework for work with bitmask more then 64bits
: size?
: similar this:
:
: #define_bitmask(name,size) char name[(size/8)+1];
: #define set_bit(bimask,no) { bitmask[(no/8)] |= 1<<(no%8); }
: #define clr_bit(bitmask,no) { bitmask[(no/8)] &= ~(1<<(no%8)); }
: static inline isset_bit(char *bitmask, no) {
: return bitmask[(no/8)] & 1<<(no%8);
: }
This isn't about 'frameworks' but rather a simple set of macros to aid
in the porting of code from other systems.
