NAME

ptree_find_node - find node with given property and value

SYNOPSIS

cc [ flag... ] file... -lpicltree [library... ]
#include <picltree.h>

int ptree_find_node(picl_nodehdl_t rooth, char *pname,
picl_prop_type_t ptype, void *pval, size_t valsize,
picl_nodehdl_t *retnodeh);

DESCRIPTION

The ptree_find_node() function visits the nodes in the subtree under
the node specified by rooth. The handle of the node that has the
property whose name, type, and value matches the name, type, and
value specified in pname, ptype, and pval respectively, is returned
in the location given by retnodeh. The argument valsize gives the
size of the value in pval. The first valsize number of bytes of the
property value is compared with pval.

RETURN VALUES

Upon successful completion, 0 is returned. On failure, a non-negative
integer is returned to indicate an error.


PICL_NODENOTFOUND is returned if there is no node that matches the
property criteria can be found.
