Tcl_StaticPackage(3tcl) Tcl Library Procedures Tcl_StaticPackage(3tcl)

NAME
Tcl_StaticPackage - make a statically linked package available via the
'load' command
SYNOPSIS
#include <tcl.h>
Tcl_StaticPackage(interp, prefix, 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 ap-
propriate initializa-
tion procedure). NULL
means the package has
not yet been incorpo-
rated into any inter-
preter.
const char *prefix (in) Prefix for library ini-
tialization function;
should be properly cap-
italized (first letter
upper-case, all others
lower-case).
Tcl_PackageInitProc *initProc (in) Procedure to invoke to
incorporate this pack-
age into a trusted in-
terpreter.
Tcl_PackageInitProc *safeInitProc (in) Procedure to call to
incorporate this pack-
age into a safe inter-
preter (one that will
execute untrusted
scripts). NULL means
the package cannot be
used in safe inter-
preters.

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 them-
selves (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 inter-
preter, one of initProc and safeInitProc will be invoked, depending on
whether the target interpreter is safe or not. initProc and safeInit-
Proc 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 ini-
tialization procedure to be invoked.
