int_set_format(struct adata *set, int way, byte *buf, unsigned int size)
/**
* int_set_format - format an &set for printing
* @set: set attribute to be formatted
* @way: style of format (0 for router ID list, 1 for community list)
* @from: starting position in set
* @buf: destination buffer
* @size: size of buffer
*
* This function takes a set attribute and formats it. @way specifies
* the style of format (router ID / community). @from argument can be
* used to specify the first printed value for the purpose of printing
* untruncated sets even with smaller buffers. If the output fits in
* the buffer, 0 is returned, otherwise the position of the first not
* printed item is returned. This value can be used as @from argument
* in subsequent calls. If truncated output suffices, -1 can be
* instead used as @from, in that case " ..." is eventually added at
* the buffer to indicate truncation.
