Tcl Library Procedures


#include <tcl.h>

Tcl_StaticPackage(interp, pkgName, initProc, safeInitProc)


Tcl_Interp *interp (in) 

If not NULL, points to an interpreter into which the package has already been loaded (that is, the caller has already invoked the appropriate initialization procedure). NULL means the package hasn't yet been incorporated into any interpreter.

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 can't be used in safe interpreters.


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.
