15 \fBint\fR \fBpicl_get_node_by_path\fR(\fBconst char *\fR\fIpiclpath\fR,
16 \fBpicl_nodehdl_t *\fR\fInodeh\fR);
22 The \fBpicl_get_node_by_path()\fR function copies the handle of the node in the
23 PICL tree specified by the path given in \fIpiclpath\fR into the location
27 The syntax of a PICL tree path is:
31 [<def_\fIpropname\fR>:]/[<\fIdef_propval\fR>[<\fImatch_cond\fR>]... ]
37 where the <\fIdef_propname\fR> prefix is a shorthand notation to specify the
38 name of the property whose value is specified in <\fIdef_propval\fR>, and the
39 <\fImatch_cond\fR> expression specifies the matching criteria for that node in
40 the form of one or more pairs of property names and values such as
44 [@<address>][?<prop_name>[=<prop_val>]... ]
50 where '@' is a shorthand notation to refer to the device address or a FRU's
51 location label and is followed by <\fIaddress\fR>, which gives the device
52 address or the location label.
55 For nodes under the \fB/platform\fR tree, the address value is matched with the
56 value of the property \fBbus-addr\fR, if it exists. If no \fBbus-addr\fR
57 property exists, the address value is matched with the value of the property
58 \fBUnitAddress\fR. To explicitly limit the comparison to \fBbus-addr\fR or
59 \fBUnitAddress\fR property, use the '?' notation described below.
62 For nodes under the \fB/frutree\fR tree, the <\fIaddress\fR> value is matched
63 with the value of the \fBLabel\fR property.
66 The expression following '?' specifies matching property name and value pairs,
67 where <\fIprop_name\fR> specifies the property name and <\fIprop_val\fR>
68 specifies the property value for properties not of type \fBPICL_PTYPE_VOID\fR.
69 The values for properties of type \fBPICL_PTYPE_TABLE\fR,
70 \fBPICL_PTYPE_BYTEARRAY\fR, and \fBPICL_PTYPE_REFERENCE\fR cannot be specified
71 in the <\fImatch_cond\fR> expression.
74 A \fB_class\fR property value of \fBpicl\fR can be used to match nodes of any
75 \fBPICL\fR classes. The class \fBpicl\fR is the base class of all the classes
79 All valid paths must begin at the root node denoted by '/'.
82 If no prefix is specified for the path, the prefix defaults to the \fBname\fR
87 Upon successful completion, 0 is returned. Otherwise a non-negative integer is
88 returned to indicate an error.
91 The value \fBPICL_NOTNODE\fR is returned if there is no node corresponding to
97 \fB\fBPICL_FAILURE\fR\fR
100 General system failure
