int bitmap_scnlistprintf(char * buf, unsigned int buflen, const unsigned long * maskp, int nmaskbits);
buf
byte buffer into which string is placed
buflen
reserved size of buf, in bytes
maskp

Output format is a comma-separated list of decimal numbers and ranges. Consecutively set bits are shown as two hyphen-separated decimal numbers, the smallest and largest bit numbers set in the range. Output format is compatible with the format accepted as input by bitmap_parselist.
The return value is the number of characters which were written to *buf excluding the trailing '\0', as per ISO C99's scnprintf.
