MrmFetchLiteral(Xm)


MrmFetchLiteral -- fetches a literal from a UID file

Syntax

#include <Mrm/MrmPublic.h>

int MrmFetchLiteral(hierarchy_id, index, display, value, type) 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 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.

type
Returns the named literal's data type. Types are defined in the include file <Mrm/MrmPublic.h>.

Return value

This function returns one of these 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.
