.\" The -*- nroff -*- definitions below are for supplemental macros used
.\" in Tcl/Tk manual entries.
.\"
.\" .AP type name in/out ?indent?
.\"	Start paragraph describing an argument to a library procedure.
.\"	type is type of argument (int, etc.), in/out is either "in", "out",
.\"	or "in/out" to describe whether procedure reads or modifies arg,
.\"	and indent is equivalent to second arg of .IP (shouldn't ever be
.\"	needed;  use .AS below instead)
.\"
.\" .AS ?type? ?name?
.\"	Give maximum sizes of arguments for setting tab stops.  Type and
.\"	name are examples of largest possible arguments that will be passed
.\"	to .AP later.  If args are omitted, default tab stops are used.
.\"
.\" .BS
.\"	Start box enclosure.  From here until next .BE, everything will be
.\"	enclosed in one large box.
.\"
.\" .BE
.\"	End of box enclosure.
.\"
.\" .CS
.\"	Begin code excerpt.
.\"
.\" .CE
.\"	End code excerpt.
.\"
.\" .VS ?version? ?br?
.\"	Begin vertical sidebar, for use in marking newly-changed parts
.\"	of man pages.  The first argument is ignored and used for recording
.\"	the version when the .VS was added, so that the sidebars can be
.\"	found and removed when they reach a certain age.  If another argument
.\"	is present, then a line break is forced before starting the sidebar.
.\"
.\" .VE
.\"	End of vertical sidebar.
.\"
.\" .DS
.\"	Begin an indented unfilled display.
.\"
.\" .DE
.\"	End of indented unfilled display.
.\"
.\" .SO ?manpage?
.\"	Start of list of standard options for a Tk widget. The manpage
.\"	argument defines where to look up the standard options; if
.\"	omitted, defaults to "options". The options follow on successive
.\"	lines, in three columns separated by tabs.
.\"
.\" .SE
.\"	End of list of standard options for a Tk widget.
.\"
.\" .OP cmdName dbName dbClass
.\"	Start of description of a specific option.  cmdName gives the
.\"	option's name as specified in the class command, dbName gives
.\"	the option's name in the option database, and dbClass gives
.\"	the option's class in the option database.
.\"
.\" .UL arg1 arg2
.\"	Print arg1 underlined, then print arg2 normally.
.\"
.\" .QW arg1 ?arg2?
.\"	Print arg1 in quotes, then arg2 normally (for trailing punctuation).
.\"
.\" .PQ arg1 ?arg2?
.\"	Print an open parenthesis, arg1 in quotes, then arg2 normally
.\"	(for trailing punctuation) and then a closing parenthesis.

.SH NAME
Tcl_StaticPackage \- make a statically linked package available via the 'load' command
.SH SYNOPSIS
.nf
\fB#include <tcl.h>\fR
.sp
\fBTcl_StaticPackage\fR(\fIinterp, pkgName, initProc, safeInitProc\fR)
.SH ARGUMENTS
.AS Tcl_PackageInitProc *safeInitProc
.AP 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.
.AP "const char" *pkgName in
Name of the package;  should be properly capitalized (first letter
upper-case, all others lower-case).
.AP Tcl_PackageInitProc *initProc in
Procedure to invoke to incorporate this package into a trusted
interpreter.
.AP 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.
.BE

.SH DESCRIPTION
.PP
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 \fBTcl_StaticPackage\fR has been invoked for a package, it
may be loaded into interpreters using the \fBload\fR command.
\fBTcl_StaticPackage\fR is normally invoked only by the \fBTcl_AppInit\fR
procedure for the application, not by packages for themselves
(\fBTcl_StaticPackage\fR 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).
.PP
When the \fBload\fR command is used later to load the package into
an interpreter, one of \fIinitProc\fR and \fIsafeInitProc\fR will
be invoked, depending on whether the target interpreter is safe
or not.
\fIinitProc\fR and \fIsafeInitProc\fR must both match the
following prototype:
.CS
typedef int Tcl_PackageInitProc(Tcl_Interp *\fIinterp\fR);
.CE
The \fIinterp\fR argument identifies the interpreter in which the package
is to be loaded.  The initialization procedure must return \fBTCL_OK\fR or
\fBTCL_ERROR\fR 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 \fBload\fR command that caused the
initialization procedure to be invoked.
