NAME
MrmFetchLiteral — Fetches a literal from a UID file
SYNOPSIS
#include <Mrm/MrmPublic.h>
Cardinal MrmFetchLiteral(
MrmHierarchy hierarchy_id,
String index,
Display *display,
XtPointer *value,
MrmCode *type);
DESCRIPTION
The MrmFetchLiteral function reads and returns the value and type of a
literal (named value) that is stored as a public resource in a single
UID file. This function returns a pointer to the value of the literal.
For example, an integer is always returned as a pointer to an integer,
and a string is always returned as a pointer to a string.
Applications should not use MrmFetchLiteral for fetching icon or color
literals. If this is attempted, MrmFetchLiteral returns an error.
hierarchy_id
Specifies the ID of the UID hierarchy that contains the
specified literal. The value of hierarchy_id was returned in
a previous call to MrmOpenHierarchyPerDisplay.
index Specifies the UIL name of the literal (pixmap) to fetch. You
must define this name in UIL as an exported value.
display Specifies the display used for the pixmap. The display
argument specifies the connection to the X server. For more
information on the Display structure, see the Xlib function
XOpenDisplay.
value Returns the ID of the named literal’s value. The function
allocates space for the returned value. The application is
responsible for managing the allocated space by calling the
appropriate deallocation function. For example, if the
returned ID symbolizes a pixmap, then the application can
recover the allocated space by calling XmDestroyPixmap.
type Returns the named literal’s data type. Types are defined in
the include file Mrm/MrmPublic.h.
RETURN
This function returns one of the following status return constants:
MrmSUCCESS
The function executed successfully.
MrmBAD_HIERARCHY
The hierarchy ID was invalid.
MrmNOT_FOUND
The literal was not found in the UIL file.
MrmWRONG_TYPE
The caller tried to fetch a literal of a type not supported
by this function.
MrmFAILURE
The function failed.
