#include <picltree.h>

int ptree_get_propval(picl_prophdl_t proph, void *valbuf,
size_t nbytes);


int ptree_get_propval_by_name(picl_nodehdl_t nodeh,
void *name, void *valbuf, size_t nbytes);


DESCRIPTION


The ptree_get_propval() function gets the value of the property specified
by the handle proph and copies it into the buffer specified by valbuf.
The size of the buffer valbuf is specified in nbytes.


The ptree_get_propval_by_name() function gets the value of the property,
whose name is specified by name, from the node specified by handle nodeh.
The value is copied into the buffer specified by valbuf. The size of the
buffer is specified by nbytes.


For volatile properties, the read access function provided by the plug-in
publishing the property is invoked.
