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PICL_STALEHANDLE is returned if the handle is no longer valid.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.
