.SH NAME
|
|
|
|
|
critbit0_allprefixed \- search a critbit tree by prefix
|
|
|
|
|
.SH SYNTAX
|
|
|
|
|
.B #include <critbit.h>
|
|
|
|
|
|
|
|
|
|
critbit0_tree cb = { 0 };

int \fBcritbit0_allprefixed\fP(critbit0_tree* \fIcb\fR,const char* \fIprefix\fR,
|
|
|
|
|
int (*handle)(const char*,void*),void* arg);
|
|
|
|
|
.SH DESCRIPTION
|
|
|
|
|
critbit0_allprefixed calls the \fIhandle\fR function on all members of
|
|
|
|
|
\fIcb\fR that start with \fIprefix\fR. It passes \fIarg\fR as second
|
|
|
|
|
argument to \fIhandle\fR.
|
|
|
|
|
|
|
|
|
|
If \fIhandle\fR returns 0, the search stops and critbit0_allprefixed
|
|
|
|
|
returns 0.
|
|
|
|
|
|
|
|
|
|
If \fIhandle\fR returns 1, the search continues and critbit0_allprefixed
|
|
|
|
|
returns 1 if all keys with the given prefix were handled.
|
|
|
|
|
|
|
|
|
|
If \fIhandle\fR returns something else, the search stops and
|
|
|
|
|
critbit0_allprefixed returns -1.
|
|
|
|
|
.SH "NOTE"
|
|
|
|
|
This function uses recursion to traverse the tree. It may require
|
|
|
|
|
nontrivial amounts of available stack space.
|
|
|
|
|
.SH "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, \fIhandle\fR was called and returned 0.
|
|
|
|
|
|
|
|
|
|
-1 if at least one key was found, \fIhandle\fR was called and returned
|
|
|
|
|
something other than 0 or 1.
