.SH "DESCRIPTION"
.PP
The \fBMrmFetchWidgetOverride\fP function
.iX "MrmFetchWidgetOverride" "description"
is the extended version of \fBMrmFetchWidget\fP\&.
It is identical to \fBMrmFetchWidget\fP, except that it
allows the caller to override the widget\&'s name and any
arguments that \fBMrmFetchWidget\fP
would otherwise retrieve from the UID file or
one of the defaulting mechanisms\&.
That is, the override argument list is not
limited to those arguments in the UID file\&.
.PP
The override arguments apply only to the widget fetched and
returned
by this function\&.
Its children (subtree) do not receive any
override
parameters\&.
.IP "\fIhierarchy_id\fP" 10
Specifies the ID of the UID hierarchy that contains
the interface definition\&.
The value of \fIhierarchy_id\fP
was returned in a previous call to \fBMrmOpenHierarchyPerDisplay\fP\&.
.IP "\fIindex\fP" 10
Specifies the UIL name of the widget to fetch\&.
.IP "\fIparent_widget\fP" 10
Specifies the parent widget ID\&.
.IP "\fIoverride_name\fP" 10
Specifies the name to override the widget name\&.
Use a NULL value if you do not want to override the widget name\&.
.IP "\fIoverride_args\fP" 10
Specifies the override argument list, exactly as given to
\fBXtCreateWidget\fP
(conversion complete and so forth)\&.
Use a
NULL value if you do not want to override the argument list\&.
.IP "\fIoverride_num_args\fP" 10
Specifies the number of arguments in
\fIoverride_args\fP\&.
.IP "\fIwidget\fP" 10
Returns the widget ID of the created widget\&.
.IP "\fIclass\fP" 10
Returns the class code identifying MRM\&'s widget class\&.
Literals identifying MRM widget class codes are defined in
the include file \fBMrm/MrmPublic\&.h\fP\&.
.SH "RETURN VALUE"
.iX "MrmSUCCESS"
.iX "MrmBAD_HIERARCHY"
.iX "MrmNOT_FOUND"

.PP
This function returns one of the following status return constants:
.IP "\fBMrmSUCCESS\fP" 10
The function executed successfully\&.
.IP "\fBMrmBAD_HIERARCHY\fP" 10
The hierarchy ID was invalid\&.
.IP "\fBMrmNOT_FOUND\fP" 10
The widget was not found in UID hierarchy\&.
.IP "\fBMrmFAILURE\fP" 10
The function failed\&.
