The Common Desktop Environment uses naming conventions similar
to those used by X and Motif. Desktop clients, desktop libraries,
and other desktop components share a common prefix for externally
visible names: dt, Dt,
or DT. Private desktop structures,
functions, and defines (found in the Common Desktop Environment
code; not for developer use) have an _dt,
_Dt, or _DT
prefix. Table 3-1 “Desktop Naming
Conventions”
lists the desktop naming conventions. Table 3-1 Desktop Naming
Conventions Name | Prefix | Example |
|---|
Desktop
clients and utilities | dt | dthelpview | Resource
names and classes | Dt | DtNhelpType, DtCHelpType | Library
names | Dt | libDtHelp | Include
references | Dt | #include <Dt/Help.h> | Public
function names | Dt | DtCreateHelpDialog | Public
data structure names | Dt | DtHelpDialogCallbackStruct | Constant
names | Dt | DtHELP_NEW_WINDOW | Environment
variables | DT | DTHELPSEARCHPATH | Private
desktop symbols (structures, functions, defines) | _dt,
_Dt, _DT | _DtHelpFunction, _DtHELP_DEFINE |
Table 3-2 “Exceptions to
Desktop Naming Conventions”
lists the exceptions to the preceding naming conventions. Table 3-2 Exceptions to
Desktop Naming Conventions Name | Prefix | Example |
|---|
Common
Desktop Environment Motif | Xm | XmCreateLabel | dtksh
Convenience Functions | Dtksh | DtkshAddButtons | ToolTalk
Messaging Service | tt (for
functions), Tt (for typedefs), TT (for constants) | tt_open,
Tt_message, TT_NOTICE | X11R6.2 | X,
Xt | XOpenDisplay, XtCreateWidget |
| | | |  | CAUTION: Do not use the prefixes dt,
Dt, DT,
_dt, _Dt,
_DT, Xm,
tt, Tt,
TT, X,
or Xt to define new symbols
in your application code. If you do, you might define one that has
already been defined—or might be defined in the future—in
the Common Desktop Environment, ToolTalk, X11, or Motif code. | | | | |
