NAME

       MrmFetchLiteral — Fetches a literal from a UID file "MrmFetchLiteral" "uil functions" "MrmFetchLiteral"

SYNOPSIS

       #include <Mrm/MrmPublic.h>
       Cardinal MrmFetchLiteral(
       MrmHierarchy hierarchy_id,
       String index,
       Display *display,
       XtPointer *value,
       MrmCode *type);
       "MRM function" "MrmFetchLiteral" "MrmFetchLiteral" "definition"

DESCRIPTION

       The  MrmFetchLiteral  function  "MrmFetchLiteral" "description" 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

       "MrmSUCCESS" "MrmBAD_HIERARCHY" "MrmNOT_FOUND" "MrmFAILURE"

       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.
