NAME
Tcl_StaticPackage - make a statically linked package available via the 'load' command
SYNOPSIS
#include <tcl.h>
Tcl_StaticPackage(interp, pkgName, initProc, safeInitProc)
ARGUMENTS
-
-
Tcl_Interp *interp (in)
If not NULL, points to an interpreter into which the package has
already been loaded (i.e., the caller has already invoked the
appropriate initialization procedure). NULL means the package
has not yet been incorporated into any interpreter.
-
-
const char *pkgName (in)
Name of the package; should be properly capitalized (first letter
upper-case, all others lower-case).
-
-
Tcl_PackageInitProc *initProc (in)
Procedure to invoke to incorporate this package into a trusted
interpreter.
-
-
Tcl_PackageInitProc *safeInitProc (in)
Procedure to call to incorporate this package into a safe interpreter
(one that will execute untrusted scripts). NULL means the package
cannot be used in safe interpreters.
DESCRIPTION
This procedure may be invoked to announce that a package has been
linked statically with a Tcl application and, optionally, that it
has already been loaded into an interpreter.
Once Tcl_StaticPackage has been invoked for a package, it
may be loaded into interpreters using the load command.
Tcl_StaticPackage is normally invoked only by the Tcl_AppInit
procedure for the application, not by packages for themselves
(Tcl_StaticPackage should only be invoked for statically
loaded packages, and code in the package itself should not need
to know whether the package is dynamically or statically loaded).
When the load command is used later to load the package into
an interpreter, one of initProc and safeInitProc will
be invoked, depending on whether the target interpreter is safe
or not.
initProc and safeInitProc must both match the
following prototype:
-
typedef int Tcl_PackageInitProc(Tcl_Interp *interp);
The interp argument identifies the interpreter in which the package
is to be loaded. The initialization procedure must return TCL_OK or
TCL_ERROR to indicate whether or not it completed successfully; in
the event of an error it should set the interpreter's result to point to an
error message. The result or error from the initialization procedure will
be returned as the result of the load command that caused the
initialization procedure to be invoked.
