MrmFetchSetValues(3X) UNIX System V MrmFetchSetValues(3X)
NAME
MrmFetchSetValues - Fetches the values to be set from literals stored in
UID files.
SYNOPSIS
#include <Mrm/MrmPublic.h>
Cardinal MrmFetchSetValues(hierarchy_id, widget, args, num_args)
MrmHierarchy hierarchy_id;
Widget widget;
ArgList args;
Cardinal num_args;
DESCRIPTION
The MrmFetchSetValues function is similar to XtSetValues, except that the
values to be set are defined by the UIL named values that are stored in
the UID hierarchy. MrmFetchSetValues fetches the values to be set from
literals stored in UID files.
hierarchy_id Specifies the ID of the UID hierarchy that contains the
specified literal. The hierarchy_id was returned in a
previous call to MrmOpenHierarchy.
widget Specifies the widget that is modified.
args Specifies an argument list that identifies the widget
arguments to be modified as well as the index (UIL name)
of the literal that defines the value for that argument.
The name part of each argument (args[n].name) must begin
with the string XmN followed by the name that uniquely
identifies this attribute tag. For example, XmNwidth is
the attribute name associated with the core argument
width. The value part (args[n].value) must be a string
that gives the index (UIL name) of the literal. You must
define all literals in UIL as exported values.
num_args Specifies the number of entries in args.
This function sets the values on a widget, evaluating the values as
public literal resource references resolvable from a UID hierarchy. Each
literal is fetched from the hierarchy, and its value is modified and
converted as required. This value is then placed in the argument list and
used as the actual value for an XtSetValues call. MrmFetchSetValues
allows a widget to be modified after creation using UID file values
exactly as is done for creation values in MrmFetchWidget.
As in MrmFetchWidget, each argument whose value can be evaluated from the
UID hierarchy is set in the widget. Values that are not found or values
in which conversion errors occur are not modified.
Each entry in the argument list identifies an argument to be modified in
the widget. The name part identifies the tag, which begins with XmN. The
value part must be a string whose value is the index of the literal.

Thus, the following code would modify the label resource of the widget to
have the value of the literal accessed by the index OK_button_label in
the hierarchy: args[n].name = XmNlabel; args[n].value =
"OK_button_label";
RETURN VALUE
This function returns one of these status return constants:
MrmSUCCESS The function executed successfully.
MrmPARTIAL_SUCCESS
At least one literal was successfully fetched.
MrmBAD_HIERARCHY
The hierarchy ID was invalid.
MrmFAILURE The function failed.
