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.
