critbit0_allprefixed(3)

NAME
critbit0_allprefixed - search a critbit tree by prefix

SYNTAX
#include <critbit.h> critbit0_tree cb = { 0 }; int critbit0_allprefixed(critbit0_tree* cb,const char* prefix,
    int (*handle)(const char*,void*),void* arg);

DESCRIPTION
critbit0_allprefixed calls the handle function on all members of cb that start with prefix. It passes arg as second argument to handle. If handle returns 0, the search stops and critbit0_allprefixed returns 0. If handle returns 1, the search continues and critbit0_allprefixed returns 1 if all keys with the given prefix were handled. If handle returns something else, the search stops and critbit0_allprefixed returns -1.

NOTE
This function uses recursion to traverse the tree. It may require nontrivial amounts of available stack space.

RETURN VALUE
1 if all keys were found and handled (or if there were no keys with that prefix). 0 if at least one key was found, handle was called and returned 0. -1 if at least one key was found, handle was called and returned something other than 0 or 1.
