ap_table_do — apply a function to each element of a table
void ap_table_do(int (*comp) (void *, const char *, const char *), void *rec, const table *t,...)
If the NULL-terminated vararg
list is empty, traverses the whole table and runs the function
comp(rec,key,value) on each key/value pair. If the
vararg list is nonempty, traverses the matching
keys (strcasecmp() is used to determine a match)
and runs the same function. Each traversal is terminated if the
function comp returns the value 0.
In either case it may happen that the comp()
function is called multiple times for the same key. The table may
again contain various entries of the same key; if the
vararg list is nonempty, the traversal is repeated
for any vararg item, even if they are equal.
