 PICL_GET_PROPVAL 3PICL "Mar 28, 2000"
 NAME
picl_get_propval, picl_get_propval_by_name - get the value of a property
 SYNOPSIS

cc [ flag... ] file... -lpicl [ library... ]
#include <picl.h>

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


int picl_get_propval_by_name(picl_nodehdl_t nodeh,
 char *propname, void *valbuf, size_t nbytes);


 DESCRIPTION

The picl_get_propval() function copies the value of the property
specified by the handle proph into the buffer location given by
valbuf. The size of the buffer valbuf in bytes is specified in
nbytes.

The picl_get_propval_by_name() function gets the value of property named
propname of the node specified by handle nodeh. The value is copied
into the buffer location given by valbuf. The size of the buffer
valbuf in bytes is specified in nbytes.

The picl_get_propval_by_name() function is used to get a reserved
property's value. An example of a reserved property is "_parent". Please
refer to libpicl(3PICL) for a complete list of reserved property names.
 RETURN VALUES

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

PICL_PROPNOTFOUND is returned if the property of the specified name does
not exist.

PICL_PERMDENIED is returned if the client does not have sufficient
permission to access the property.

PICL_STALEHANDLE is returned if the handle is no longer valid.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.
This error may be returned for a previously valid handle if the daemon was
brought down and restarted. When this occurs a client must revalidate any saved
handles.
