 PTREE_CREATE_PROP 3PICLTREE "Mar 28, 2000"
 NAME
ptree_create_prop, ptree_destroy_prop - create or destroy a property
 SYNOPSIS

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

int ptree_create_prop(ptree_propinfo_t *pinfo, void *valbuf,
 picl_prophdl_t *proph);


int ptree_destroy_prop(picl_prophdl_t proph);


 DESCRIPTION

The ptree_create_prop() function creates a property using the information
specified in pinfo, which includes the name, type, access mode, and size
of the property, as well as the read access function for a volatile property.
The value of the property is specified in the buffer valbuf, which may be
NULL for volatile properties. The handle of the property created is
copied into the location given by proph. See
libpicltree(3PICLTREE) for more information on the structure of
ptree_propinfo_t structure.

The ptree_destroy_prop() function destroys the property specified by the
handle proph. For a table property, the entire table is destroyed. The
property to be destroyed must have been previously deleted.
 RETURN VALUES

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

PICL_STALEHANDLE is returned if the handle is no longer valid. This
occurs if the PICL tree was refreshed or reinitialized.

PICL_INVALIDHANDLE is returned if the specified handle never existed.
