◆ stringbuffer_append_ordinal()

void stringbuffer_append_ordinal ( StringBuffer sb,
const int  n 
)

Turns a cardinal number (e.g. 7) into an ordinal number (e.g. "seventh") and appends it to a caller-supplied StringBuffer. Works only on numbers 0 <= n < 100; outside that range just returns the cardinal number as a string.

Parameters
sbStringBuffer to append the result to.
nNumber to ordinalize.

◆ stringbuffer_append_spelldesc()

static void stringbuffer_append_spelldesc ( StringBuffer sb,
const object spell 
)
static

Append a terse description of the spell's name, level, discipline, and paths to a stringbuffer. What comes out is something like: "medium fireball (a third level pyromancy) (paths: Fire)" this is used in both spellbook_type_describe() to generate the one-line description for a spellbook, and in spellbook_type_apply to summarize what the spellbook contains if you don't ID it until you start reading it.

Parameters
sbThe StringBuffer to append to
spellThe spell to describe
