- int bitmap_scnprintf(char * buf, unsigned int buflen, const unsigned long * maskp, int nmaskbits);
- byte buffer into which string is placed
- reserved size of buf, in bytes
- pointer to bitmap to convert
- size of bitmap, in bits
Exactly nmaskbits bits are displayed. Hex digits are grouped into comma-separated sets of eight digits per set. Returns the number of characters which were written to *buf, excluding the trailing \0.
