.TH QCCWAVZEROTREEMAKEFULLTREE 3 "QCCPACK" ""
.SH NAME
QccWAVZerotreeMakeFullTree
QccWAVZerotreeMakeEmptyTree
 \- 
create full or empty zerotree structure
.SH SYNOPSIS
.B #include "libQccPack.h"
.sp
.BI "int QccWAVZerotreeMakeFullTree(QccWAVZerotree *" zerotree );
.br
.BI "int QccWAVZerotreeMakeEmptyTree(QccWAVZerotree *" zerotree );
.SH DESCRIPTION
.LP
.BR QccWAVZerotreeMakeFullTree()
makes
.I zerotree
"full" by marking every symbol in
.I zerotree
as significant; i.e., it sets every node in
.I zerotree
to
.BR QCCWAVZEROTREE_SYMBOLSIGNIFICANT .
.LP
.BR QccWAVZerotreeMakeEmptyTree()
makes
.I zerotree
"empty" by marking every symbol in
.I zerotree
as "null" via a call to
.BR QccWAVZerotreeMakeSymbolNull (3).
.LP
If
.I zerotree
has not been allocated prior to calling these routines,
.BR QccWAVZerotreeAlloc (3)
is called before manipulating the zerotree symbols.
In the case of
.BR QccWAVZerotreeMakeEmptyTree() ,
.BR QccWAVZerotreeMakeFullTree()
is called after allocating so that all zerotree nodes are set to
valid symbols, specifically
.BR QCCWAVZEROTREE_SYMBOLSIGNIFICANT ,
before making them "null".
.SH "RETURN VALUE"
These routines return 0 on success, and 1 on failure.
.SH "SEE ALSO"
