#include <picltree.h>

int ptree_find_node(picl_nodehdl_t rooth, char *pname,

     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.
