cc [ flag... ] file... -lpicltree [ library... ] #include <picltree.h> int ptree_update_propval(picl_prophdl_t proph, void *valbuf, size_t nbytes);
int ptree_update_propval_by_name(picl_nodehdl_t nodeh, char *name, void *valbuf, size_t nbytes);
The ptree_update_propval() function updates the value of the property specified by proph with the value specified in the buffer valbuf. The size of the buffer valbuf is specified in nbytes.
The ptree_update_propval_by_name() function updates the value of the property, whose name is specified by name, of the node specified by handle nodeh. The new value is specified in the buffer valbuf, whose size is specified in nbytes.
For volatile properties, the write access function provided by the plug-in publishing the property is invoked.
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PICL_STALEHANDLE is returned if the handle is no longer valid.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.
PICL_VALUETOOBIG
Value too big
PICL_NOTPROP
Not a property
PICL_NOTNODE
Not a node
PICL_INVALIDHANDLE
Invalid handle
PICL_STALEHANDLE
Stale handle
PICL_PROPNOTFOUND
Property not found
